Choose a mattress size before comparing comfort

Twin

Decision: Twin is listed by 24 reviewed families/plans, including the exact Level Two Hybrid, both the original Dream Weaver and Dream Weaver Hybrid, Novaform Back Support Plus, ComfortGrande Advanced foam and SoFresh Plus; none of the four Black Series pages lists Twin, which is distinct from their Twin XL selector. Confirm the exact family and size selector in the review links for the Series One, Series Two, Series Three and Series Four as well.

Beautyrest lists Twin for both the 12-inch BR800 Medium and the Silver BRS900 Medium Firm. The latter's exact manufacturer height is 11.75 inches while Costco rounds the listing to 12; verify the retailer's selected size and final item.

The current Dream selector lists Twin and its manufacturer specification gives a 12-inch profile; Snow's selector begins at Twin XL. Their official structured product data also lists different size-specific codes, but that does not establish personal fit or the Split King package contents. Read the Dream assessment and compare the Snow size list before treating Twin and Twin XL as interchangeable.

Casper's selector includes Twin for The One, but no exact size code was captured; compare the model review and confirm the code and foundation at order time.

Cloud One's exact selector also lists Twin, but no size-level code or weight was captured. Compare the Cloud One review and confirm the selected frame and offer.

Check the frame's stated length and width, center support and room access before choosing among them. Youth is a child-specific, 10-inch family; it is not simply a smaller adult option. For other construction starting points, compare Classic and Contour5.

Open the finder with only Twin selected. Compare the Purple Mattress and PurplePlus with the PurpleFlex 8-inch profile, Rejuvenate's five-size list, which starts at Twin XL, RestorePlus Cool Touch's Twin XL-and-larger list, RestorePremier's size list, Youth, Classic and Contour5.

Exact model details and limits: Murphy Bed Mattress review; Bunk & Trundle review. Check the frame and model-specific conditions before treating a result as a setup recommendation.

The new Novaform Twin variants are not a single construction: Advanced Back Support Plus is a Firm 12-inch foam plan; ComfortGrande Advanced foam is Medium at 14 inches; and SoFresh Plus is Medium at 10 inches. Each exact endpoint lists Twin; verify the selected offer, frame dimensions, delivery route and base separately.

Twin, Medium and a 10-inch maximum

Decision: When Twin, Medium, side-position guidance, a maximum of 10 inches, a 365-night minimum and a $99 return-fee ceiling are all required, the current matcher returns two Saatva plans: Murphy Bed Mattress and Bunk & Trundle. This is a narrow shared-selector result, not evidence that their use cases overlap.

The Murphy model is 10 inches, 45 lb in Twin and intended only for Murphy, wall or pull-down beds; Saatva explicitly excludes adjustable bases. Bunk & Trundle is 7 inches and 34 lb in Twin, primarily intended for bunk/trundle use. Its FAQ's Murphy mention conflicts with its main setup section; ask about the exact frame rather than treating this as approval. Both use Saatva’s 365-night/$99 policy, which is not a no-fee return.

Open the finder with this exact Twin, feel, position, height and policy combination. Compare the Murphy Bed Mattress and Bunk & Trundle assessments, then verify the exact bed maker’s size, weight, clearance and retention rules.

Twin XL

Decision: Twin XL appears in 42 reviewed plans, including all four Beautyrest Black Series families, the Level Two Hybrid, both Dream Weaver families, and Casper Dream, Snow, Dream Max, Snow Max, The One and Cloud One; Snow and both Maxes omit Twin. The exact Black pages list Twin XL, Full, Queen, King and California King, while Level Two Hybrid lists six sizes from Twin through Cal King.

Beautyrest lists Twin XL for both its BR800 Medium and Silver BRS900 Medium Firm pages. These are different 800- and 900-series coil models; the page-level sizes do not establish a Costco size-specific SKU or a live offer.

Dream Max and Snow Max each list Twin XL at 14 inches, but their names and feel packages are not interchangeable. See the Dream Max and Snow Max assessments and check the exact offer.

Dream and Snow each list Twin XL and a 12-inch mattress profile. Casper's structured product data lists a separate SKU and GTIN for each size; it does not explain the number of pieces in either Split King offer. Review Dream and Snow and verify the exact offer.

Casper also lists Twin XL in the The One selector; its size-level product code remains unconfirmed, so verify the selected offer and frame dimensions in the model review.

Cloud One lists Twin XL as a standalone size. Its selector has no Split King SKU, although the separate current Adjustable Bundle provides a package route with two Twin XL Cloud One pieces; its base-name conflict and unclear protector quantity still need an order check. See the Cloud One review.

The separate 2023 RejuvenatePlus and RejuvenatePremier tables also name Twin XL, but both old versions are 16.5-inch references with no verified current offer or code; see the 2023 Plus and 2023 Premier reviews rather than treating them as current finder matches.

Twin XL is also the half-size used in several Split King arrangements. If you need only one Twin XL, do not assume a two-piece Split King package is the same purchase.

Open the finder with only Twin XL selected. Compare Duke, Duchess, Monarch and Crown with current Rejuvenate, RejuvenateUltimate's 17.5-inch Twin XL, RejuvenatePremier and RejuvenatePlus; also compare Restore Cool Touch, the separate RestorePlus Cool Touch and the separate RestorePremier Cool Touch, plus The Purple Mattress, PurplePlus, standard Restore, RestorePlus, direct RestorePremier and PurpleFlex with Youth, Memory Foam Hybrid and Classic.

Exact model details and limits: Bunk & Trundle review. Check the frame and model-specific conditions before treating a result as a setup recommendation.

Full

Decision: Full appears in 40 reviewed plans, including all four Beautyrest Black Series families, the Level Two Hybrid, both Dream Weaver families and Novaform’s Back Support Plus, ComfortGrande Advanced foam and SoFresh Plus; each exact Beautyrest page lists Full. Check the selected seller and model code rather than assuming all families or variants match.

Beautyrest's exact pages also list Full for the BR800 Medium and Silver BRS900 Medium Firm. Confirm that the seller offers Full for the exact selected mattress; the Costco item numbers are not size-level identifiers.

Both exact Costco selectors include Full: the foam page lists Item 1748799 and the hybrid lists Item 1800512. These are separate all-foam and foam-and-coil products, not two comfort options for one mattress; check the exact live selector and service area. Read the foam and hybrid assessments.

The 14-inch Dream Max and Snow Max both list Full; Casper's structured product data provides a size-specific SKU and GTIN for each model, while Split King package contents remain a separate check.

Dream and Snow each list Full with a 12-inch profile, but they differ in feel and features: Dream is the responsive Medium hybrid; Snow is the conforming Medium cooling hybrid. Read Dream and Snow; confirm that the selected size code, seller and package match the intended family.

The One's current Casper selector includes Full; its exact order code was not recorded. See the review before selecting an offer.

Cloud One also has a Full selector option; the exact size code and weight remain unknown. See its model review and confirm the current package.

Novaform's two Legacy Premier Support feel pages each list Full at 53 × 75 × 14 inches; the separate Medium and Firm plans have different top/support descriptions, and the manufacturer pages do not expose populated SKU/barcode values. These are page-listed dimensions, not measurements; verify the exact feel, size and retailer offer. Read the Novaform Legacy Premier Support review.

Measure your existing support surface and the path through doors or stairs. The candidates differ in foam/coil construction and height; size availability alone does not identify a preferred feel.

Open the finder with only Full selected. Compare Purple's manufacturer-listed Full Restore Cool Touch code, the manufacturer-listed RestorePlus Cool Touch Full and the seller-listed Full RestorePremier Cool Touch configuration with the excluded current Rejuvenate size list, The Purple Mattress, PurplePlus, standard Restore, direct RestorePlus and PurpleFlex; the separate direct RestorePremier page also does not list Full. Compare these with Youth, Latex Hybrid, Contour5 and Classic.

Exact model details and limits: Murphy Bed Mattress review; Bunk & Trundle review. Check the frame and model-specific conditions before treating a result as a setup recommendation.

Novaform’s exact current Full options include 12-inch Firm Back Support Plus, 14-inch Medium all-foam ComfortGrande Advanced and 10-inch SoFresh Plus. The ComfortGrande hybrid and Serafina endpoints list Queen/King, not Full. These are model-specific manufacturer variants, not a statement about retailer stock.

Queen

Decision: Queen is listed for 52 reviewed plans, including all four Beautyrest Black Series families, the Level Two Hybrid, both Dream Weaver families and Novaform families or configurations spanning 10, 12 and 14 inches. All nine reviewed current Beautyrest families name Queen; confirm the family, selected feel and exact size SKU before comparison.

Beautyrest lists Queen for both the 12-inch BR800 Medium and Silver BRS900 Medium Firm. The BR800 is the maker's Medium/800-series plan; the BRS900 is a distinct Medium Firm/900-series plan whose Costco title and specification fields conflict. Verify the exact size and listing before ordering.

The exact Costco foam selector lists Queen Item 1748800 and the hybrid selector lists Queen Item 1788193. Both are 12-inch profiles, but one is all foam with Costco's Medium label and the other is a foam-and-coil design whose Medium Firm/Medium label conflict remains unresolved. Compare the foam and hybrid reviews rather than treating the shared retailer name as one offer.

Both Max families list Queen at a 14-inch profile: compare Dream Max's responsive/lively Medium Soft plan with Snow Max's conforming Medium Soft cooling package. Confirm size codes, package, seller and base separately.

Both Dream and Snow list Queen at a 12-inch mattress profile; their feel, cooling package and size-level identifiers remain distinct. Casper's structured product data publishes the separate Queen SKUs and GTINs. Compare the Dream assessment with Snow and confirm the seller's selected size.

Casper The One has a Queen selector choice, but the exact size-level code was not captured. Confirm the offer rather than treating the page's family URL as a Queen SKU; see the model assessment.

Cloud One's current selector also lists Queen. The exact order code and weight remain unconfirmed; see the Cloud One assessment.

Novaform's exact Medium and Firm Legacy Premier Support pages list Queen at 60 × 80 × 14 inches, but their pages do not publish populated SKU/barcode values or confirm that a retailer item bridges to both feel choices. Legacy Elite Premier is a distinct Queen option at 60 × 80 × 16 inches and 133.5 lb; its size data likewise has no populated SKU/barcode. These are maker-listed mattress-only specifications, not measurements. Read the Legacy Premier Support review and Legacy Elite Premier review, recheck the selected model and seller, and include the base and frame in the finished height. The separate Platinum family lists Queen at 60 × 80 × 16.5 inches and 173.5 pounds; check the full bed stack and delivery path in the Platinum review.

PurpleRenew’s current ProductGroup lists Queen code 10-21-23649; its size table shows 80 × 60 inches, 109 lb and 11 inches, while its separate card says 11.5 inches. That is a current size match but not a settled height claim. Read the PurpleRenew assessment and verify the selected code and delivered profile if clearance matters.

The two separate 2023 RejuvenatePlus and RejuvenatePremier tables also name Queen at a 16.5-inch profile, but those exact-generation offers and codes were not verified; the Plus and Premier pages are historical references, not finder results.

Check the frame's usable dimensions, center support, route into the bedroom and total setup height. Saatva lists the Zenhaven Queen at 125 pounds and the Solaire Queen at 114 pounds; these are manufacturer weights, not independent measurements.

Open the finder with only Queen selected. Compare Duke, Duchess, Monarch and Crown with RejuvenatePremier, RejuvenatePlus, RejuvenateUltimate's Queen profile, current Rejuvenate, Restore Cool Touch, RestorePlus Cool Touch and the separate RestorePremier Cool Touch, plus PurplePlus, Purple Mattress, standard Restore, direct RestorePlus, the distinct online RestorePremier and PurpleFlex with Zenhaven, Classic, Contour5 and Solaire.

Exact model details and limits: Murphy Bed Mattress review. Check the frame and model-specific conditions before treating a result as a setup recommendation.

Five new Novaform family records have Queen variants: Firm Back Support Plus (12 inches), Medium ComfortGrande all-foam (14 inches), Medium ComfortGrande hybrid (14 inches), Serafina Plush/Medium/Firm (14 inches; distinct exact feel pages), and Medium SoFresh Plus (10 inches). The staged images do not establish delivery contents, and the 14-, 12- and 10-inch values exclude a base.

King

Decision: King is listed by 51 reviewed plans, including all four Beautyrest Black Series pages, the Level Two Hybrid, both Dream Weaver families and the assessed Novaform selector set. The four Black pages list standard King; that is distinct from Split King. Level Two Hybrid also lists only standard King, not a split arrangement.

Beautyrest's exact model pages list King for the BR800 Medium and Silver BRS900 Medium Firm. These source sizes are not a promise of Costco stock, split-king availability or the same seller package.

The exact Costco foam selector lists King Item 1748801; its distinct hybrid selector lists King Item 1788194. The 12-inch profiles belong to separate products and the foam page's source-backed Medium label does not resolve the hybrid page's internal Medium Firm/Medium disagreement. See the foam and hybrid assessments before checking the chosen frame and offer.

The 14-inch Dream Max and Snow Max both list King; these mattress selections differ from a bundle's base/protector contents.

Dream and Snow both list King at 12 inches, with different constructions and feels; their structured product data publishes distinct size-level codes, but not every seller/package detail. Read Dream and Snow before checking the chosen frame and exact offer.

The One's selector lists King, but no size-level Casper code was captured; use the Casper assessment and verify the exact package.

Cloud One's exact selector lists King, but no size-level code or weight was recorded. Read the Cloud One review before comparing the package and frame.

Novaform's exact Legacy Premier Support Medium and Firm pages list King at 76 × 80 × 14 inches. The separate Legacy Elite Premier lists a King at 76 × 80 × 16 inches and 170 lb, while its public variant data has no populated SKU/barcode; all figures are maker-listed mattress specifications, not measurements. None of these pages names adjustable-base approval. Compare the distinct Legacy Premier Support and Legacy Elite Premier reviews and verify the selected model, seller, support frame and route. The separate Platinum plan lists a 76 × 80 × 16.5-inch King at 221.8 pounds; check its frame and delivery path in the Platinum assessment.

PurpleRenew’s King code is 10-21-23650; Purple’s table lists 80 × 76 inches and 138 lb, but its own page conflicts between 11 and 11.5 inches. See the separate assessment; treat King availability separately from strict height fit.

The separate 2023 RejuvenatePlus and RejuvenatePremier support tables also name King, each with a 16.5-inch profile, but no current exact-version offer or code was confirmed. Read the 2023 Plus and 2023 Premier references separately from their current counterparts.

Confirm the complete frame and sleeping-area measurements, not a retailer's shorthand. Both makers state that their Upper-Flex mattress needs the corresponding Upper-Flex adjustable base; Zenhaven lists a 30-inch split from the head. These configurations are distinct from standard King and two-piece Split King.

Open the finder with only King selected. Compare the separate Duke, Duchess, Monarch and Crown sizes with RejuvenatePremier, RejuvenatePlus, RejuvenateUltimate's King profile, current Rejuvenate, Restore Cool Touch, RestorePlus Cool Touch and the RestorePremier Cool Touch retailer version, plus The Purple Mattress, PurplePlus, standard Restore, direct RestorePlus, the distinct online RestorePremier, PurpleFlex, Zenhaven, Solaire, Classic and Latex Hybrid.

Novaform’s current endpoint lists King for Advanced Back Support Plus, ComfortGrande Advanced foam, ComfortGrande Advanced Hybrid, each of the three Serafina plans, and SoFresh Plus. Confirm the selected plan and item in the exact live seller selector; King does not establish Split King quantities.

Split King

Decision: In this reviewed library, the matcher lists twenty-nine families for Split King, including Casper Cloud One only through the currently listed Adjustable Bundle; none of the four Black Series pages lists Split King. Casper's guide defines the usual setup as two 38 × 80-inch Twin XL mattresses making a 76 × 80-inch King footprint, while the Max bundle pages do not specify their exact included pieces. Compare the Series One, Series Two, Series Three and Series Four reviews before treating a different Black size as a split set.

Purple's separate New PurpleFlex, New Purple Mattress and New PurplePlus entries also list Split King with distinct 2027 size codes. A size selector does not confirm the exact pair, frame or base supplied with a current offer; check the New PurpleFlex, New Purple Mattress and New PurplePlus assessments.

The exact Dream Weaver Hybrid product group lists only standard Twin, Twin XL, Full, Queen, King and California King for both plans; it has no Split King SKU or package. See the SKU-specific review rather than inferring a pair from its King size.

For Casper's Dream Max and Snow Max, the standalone selector includes Split King and size-level codes identify a size choice, not a full shipping manifest. Their Dream/Snow/Adjustable Max bundle pages also list Split King but do not clearly enumerate mattress-piece quantities; confirm the exact product, two halves, base and protector in the final offer rather than inferring package contents from a name.

Casper's Dream and Snow selectors list Split King; Snow begins at Twin XL while Dream also lists Twin. The maker's guide defines the usual split as two Twin XLs, but their product-page aggregate size rows do not say how those pieces are packaged, and a mattress-only selection does not include a base. Compare their separate feel and construction plans, then verify the exact order contents.

Casper The One's selector lists Split King, and its size-level identifiers are documented. The separate current Adjustable Bundle offers The One or Cloud One and describes two Twin XL mattress pieces for Split King. Its copy names an Adjustable Base, while several size-specific rows say Adjustable Base Pro; the protector line does not establish a quantity. That confirms the mattress pair for this named package only, not a clean base identity or the contents of a mattress-only or Max bundle. An older One Adjustable Bundle capture had a more specific component list, but its current direct route has no visible selector/specifications, so those details are historical rather than a current order manifest. See the The One assessment for its one-feel, 11-inch details.

Cloud One's standalone product selector has no Split King size code, but the current Adjustable Bundle lists Cloud One and explicitly describes two Twin XL mattress pieces for that package size. The size finder therefore includes a documented current package route, not an unlisted standalone size code; the base labels conflict, and protector quantity is not clear. The different One Adjustable Bundle route was captured earlier with its own component manifest, but the live route is currently contentless and that older manifest is not a current offer claim. Read the Cloud One review and check the exact package/base terms before depending on it.

Both 2023 RejuvenatePlus and 2023 RejuvenatePremier tables also name Split King, but their two-row measurements do not unambiguously define delivered pieces. They remain 16.5-inch historical references with no verified current offer; see the Plus and Premier reviews instead of assuming Twin XL halves.

RejuvenateUltimate Split King is code 10-21-24202 and two 80 × 38 × 17.5-inch pieces at 126 lb each. Purple's exact FAQ names two Smart Base families, but do not generalize this to Purple Adjustable Base or assume a particular two-base package is included; confirm both pieces and their exact setup. Review the RejuvenateUltimate assessment before comparing its unusually tall profile with lower split options.

For Casper's split adjustable-frame setup, the official base FAQ says each side moves independently when the setup uses two Twin XL mattresses; its Split King base frames use two remotes and one frame, and Casper says the frames can also be synchronized. The current Adjustable Bundle explicitly describes the The One or Cloud One Split King mattress selection as two Twin XL pieces, but its copy and size-specific table conflict on whether the base is Adjustable Base or Adjustable Base Pro, and its protector line does not resolve quantity. The earlier One Adjustable Bundle capture listed an Adjustable Base Pro at 75 × 79 × 15.5 inches, a 750-lb maximum, leg-dependent platform heights (8.5, 10.5 or 15.5 inches), two Twin XL mattresses and one 76 × 80-inch protector; its current direct route now shows no package selector/specifications, so those figures remain historical evidence, not a current manifest. The base's old listed maximum is not a sleeper-weight recommendation or per-side allowance, and platform height is separate from mattress profile. The Adjustable Pro Bundle page offers Dream or Snow and lists a Twin XL mattress specification, Split King base and Twin XL protector, but does not expressly state quantities; the Dream/Snow and Max bundle pages likewise need an exact component manifest. Do not infer those bundle contents from a standalone family size.

Confirm whether the order is two Twin XL mattresses, which base is required or recommended, whether each half adjusts independently, and whether one feel works for both halves. Current RejuvenatePremier lists Split King code 10-21-24201 as two 80 × 38 × 15.5-inch pieces at 117 lb each; Purple names Premium Smart Base and Premium Plus Smart Base but excludes its Purple Adjustable Base, and warranty support calls for two Twin XL bases. RejuvenatePremier's named approvals are not generic; verify the exact base and size. Current Rejuvenate is listed as two 80 × 38 × 14.5-inch pieces, code 10-21-24199, 104 lb each; its adjustable-base wording conflicts, so size availability does not establish compatibility. RejuvenatePlus lists Split King code 10-21-24200 as two 80 × 38 × 15.5-inch pieces at 112 lb each, but Purple Support's dimensions table instead says 16.5 inches; its base FAQ names Premium Smart Base and Premium Plus Smart Base, yet the exact split-base pairing still needs confirmation. Purple's exact Restore Cool Touch page lists a separate Split King code (10-21-24015), and the seller describes Split King as two Twin XL pieces. Its exact size pieces and support pairing still need confirmation. The other direct Purple families also have model-specific split codes and conditional base rules: standard Restore is two 80-by-38-inch pieces at 11.5 inches and 72 lb apiece; direct RestorePlus uses that footprint at 13 inches and 95 lb each; direct RestorePremier publishes a combined product and shipping entries but not every half dimension or base layout. The distinct RestorePlus Cool Touch page lists Twin XL, Full, Queen, King and California King only, so it cannot satisfy a Split King requirement. Contour5 and Zenhaven specify Saatva Split King base pairings; Solaire requires its matching split base. Zenhaven's two faces are not separate left/right selectors.

Open the finder with only Split King selected. Compare the retailer-described two-Twin-XL Crown package with current Rejuvenate, RejuvenatePremier, RejuvenatePlus and the 17.5-inch RejuvenateUltimate, with Restore Cool Touch and the excluded RestorePlus Cool Touch size list, The Purple Mattress, PurplePlus, standard Restore, direct RestorePlus, direct RestorePremier, PurpleFlex, Zenhaven, Solaire, HD and Contour5.

Split King with a Medium-soft feel

Decision: Split King with Medium-soft maker guidance returns Casper Cloud One through its current Adjustable Bundle, Dream Max, Snow Max, RejuvenatePremier and direct RestorePlus.

These are not five interchangeable feels or package routes. Cloud One's standalone selector lacks Split King, but the current Adjustable Bundle states two Twin XL Cloud One mattress pieces; its base name conflicts between Adjustable Base and Adjustable Base Pro, and its protector quantity is not clear. The separate One Adjustable Bundle had a detailed earlier capture, but its current direct route is contentless, so do not use that saved manifest as a current offer claim. Dream Max and Snow Max have separate 14-inch plans; Dream Max also distinguishes standard Cozy from its integrated QuickCool cover. Purple's RestorePlus is a 13-inch Medium-soft plan, while RejuvenatePremier is 15.5 inches and has its own named-base limits. Casper's Split King guide warns that the mattress halves should have matching profile height; check feel, height, exact base and package together rather than treating the questionnaire's shared label as a comfort prediction.

Open the finder with Split King and Medium-soft selected. Compare the bundle-only Cloud One with Dream Max, Snow Max, RestorePlus and RejuvenatePremier.

California King

Decision: California King is listed by 43 reviewed plans, including all four Beautyrest Black Series pages, the Level Two Hybrid and both Dream Weaver families. The Black families, Level Two Hybrid and Dream Weaver profiles each retain their own size-level maker codes; among the newly reviewed Novaform rows, only the exact ComfortGrande Advanced all-foam endpoint includes California King. Verify the exact product and seller selector rather than transferring codes between families.

Beautyrest also names California King for both the BR800 Medium and Silver BRS900 Medium Firm. The exact retailer's selector and current offer still need to be checked; neither Costco item number identifies an individual size variant.

The exact Costco foam selector lists California King Item 1748802; the separate hybrid selector lists California King Item 1788195. Costco's captured foam specification table does not include a Cal King dimension, while its hybrid table does; do not transfer the hybrid dimensions or the Casper maker-page foam values between products. See the foam and hybrid reviews.

The separate 14-inch Dream Max and Snow Max selectors both list California King. Casper's structured product data publishes size-specific identifiers for each; the profile excludes the base stack.

Both Dream and Snow list California King at a 12-inch mattress profile and have distinct size-level SKU/GTIN records in Casper's product data. Compare Dream and Snow; don't transfer size-specific details between Casper families.

The One's size selector lists California King, but no exact Casper size code was captured; confirm the current package and actual frame dimensions in the model review.

Cloud One's selector also lists California King, but its exact size-level code and weight were not captured. Check the Cloud One assessment and verify the current order dimensions.

PurpleRenew’s current California King code is 10-21-23651; its table lists 84 × 72 inches and 137 lb, with the same unresolved 11/11.5-inch height conflict. Read the PurpleRenew assessment before relying on a close-clearance comparison.

The two 2023 Plus and Premier tables name Cal King at 16.5 inches, but their row formatting does not clearly separate the width and height. Their model-specific assessments explain why these historical entries are not current finder matches and why exact dimensions need confirmation.

The page names and exact product dimensions need to agree with the frame, sheets and room. Compare height and construction only after confirming this size-specific requirement.

Open the finder with only California King selected. Compare the distinct Duke, Duchess, Monarch and Crown with RejuvenatePremier, RejuvenatePlus, RejuvenateUltimate, current Rejuvenate, Restore Cool Touch, RestorePlus Cool Touch, the separate RestorePremier Cool Touch and direct RestorePremier, separately from The Purple Mattress, PurplePlus, standard Restore, direct RestorePlus, Classic and Contour5.

The exact Novaform offer newly confirmed for this choice is the 14-inch Medium ComfortGrande Advanced all-foam plan; its five-size endpoint explicitly includes California King. The separate Back Support Plus, Serafina and SoFresh specifications contain California King hints, but exact current endpoints do not, so they are not counted as available sizes.

Split California King

Decision: Among all twenty-two reviewed families, the Saatva Classic and Solaire selectors are the only ones listing Split California King; the four Black Series pages list California King but not its split variant. Cloud One's selector, like the other reviewed non-Saatva selectors, does not list that size. Base Rejuvenate, RejuvenatePlus, RejuvenatePremier and RejuvenateUltimate, PurplePlus, Restore, direct RestorePlus, all three Cool Touch editions, RestorePremier and the other reviewed selectors also do not list it. Read the Series One, Series Two, Series Three and Series Four reviews.

Dream Weaver Hybrid has Cal King as its standard sixth size for both profiles, but its exact two-profile selector does not offer Split California King. The SKU-level review distinguishes those codes from a split set.

RejuvenateUltimate's current product page lists Split King, but not Split California King; its 17.5-inch Split King consists of two Twin XL-sized pieces. See the exact size and setup assessment.

Cloud One lists California King but not Split California King; its page's six-size selector does not show a split variant. See the Cloud One assessment before treating a general California King name as split-size compatibility.

Before ordering, confirm that the frame uses the same split dimensions and that the mattress and adjustable-base pairing match your setup. Solaire says its Split Cal King requires the corresponding Saatva split base. A size label does not establish an identical pair, package or base.

Open the finder with only Split California King selected. Compare the Classic and Solaire assessments with the excluded current Rejuvenate size list.

Maximum mattress height

Decision: At an inclusive maximum, Novaform SoFresh Plus enters at 10 inches, Advanced Back Support Plus at 12 inches, and the three separate 14-inch ComfortGrande foam, ComfortGrande hybrid and Serafina families at 14 inches. Beautyrest's 12-inch BR800 and Level Two Hybrid, plus maker-listed 11.75-inch BRS900, clear a 12-inch maximum but not 11.5 inches; the Black Series One–Four pages provide no numeric mattress height and cannot pass a height ceiling. Read the Series One, Series Two, Series Three and Series Four reviews; documented profiles are mattress-only.

Dream Weaver Hybrid has two separate maker-listed profiles: its 11.5-inch Medium enters at an 11.5-inch maximum; the 12.5-inch Plush is excluded at 12 inches and enters at 12.5. A maximum of 12.5 inches or more admits both Hybrid plans. These numbers are mattress-only. Read the two-profile review and compare the exact 11.5-inch, 12-inch and 12.5-inch maximum searches.

The maximum-height input covers 7 through 17.5 inches in half-inch steps, spanning the smallest individually reviewed profile. A 7-inch Bunk & Trundle profile meets the lower boundary; the distinct 8-inch New PurpleFlex does not fit a 7.5-inch cap but meets the inclusive 8-inch cap. Murphy Bed Mattress remains exactly 10 inches. Dream and Snow enter at 12 inches, while the 14-inch Dream Max and Snow Max enter at the inclusive 14-inch ceiling. These are mattress-only profiles, not total bed elevation. Purple's New Purple Mattress and New PurplePlus are left out of hard height matching because their collection cards and New product details disagree; PurpleRenew's 11/11.5-inch height conflict also remains unknown.

Decision: The New PurpleFlex entry lists an 8-inch profile, so it fails a 7.5-inch maximum and meets the inclusive 8-inch maximum; the other New Purple models remain unclassified for this numeric fit.

Compare the exact 7.5-inch ceiling with the 8-inch ceiling. The 7-inch Bunk & Trundle fits either; the New PurpleFlex assessment documents the 8-inch boundary. These are maker-listed profiles, not independent measurements or finished-bed clearance.

Novaform lists both the Medium and Firm Legacy Premier Support plans at 14 inches: a 13.5-inch maximum excludes them and 14 inches admits them at the inclusive boundary. That is mattress thickness only, not a base or finished-bed measurement; review the exact model assessment before checking the height against a frame.

Novaform's separate Platinum family is 16.5 inches in Queen or King; an exact 16.5-inch ceiling admits its single Medium plan, while a 16-inch ceiling excludes it. Its Queen listing is 173.5 pounds, so measure the frame stack and delivery path separately. Read the Platinum assessment before relying on the exact profile.

The distinct Novaform Legacy Elite Premier plan is listed at 16 inches in Queen or King. It falls outside a 15.5-inch maximum but enters at the inclusive 16-inch cap, while the 16.5-inch Platinum remains above that tighter ceiling. These are mattress-only source figures; read the Legacy Elite Premier assessment and add the support stack.

The distinct Costco Cooling Select foam and hybrid plans are each listed at 12 inches. Neither fits a maximum below 12; both enter at the inclusive 12-inch cap and remain under larger caps. The foam is retailer-labeled Medium, while the hybrid's comfort label remains conflicted. Compare the foam and hybrid evidence and use the exact finder height condition rather than adding a foundation.

For the Casper boundary, its two distinct foam models share a listed 11-inch profile but not a feel: Cloud One is Medium Soft and The One is Medium-Firm. See the Cloud One assessment and The One review. This is mattress height only; add the base and foundation separately.

PurpleRenew is deliberately not counted inside or outside any strict height window. Its exact page’s table and profile label say 11 inches, while separate card data says 11.5 inches; until Purple clarifies which applies, the finder leaves its plan height unknown. Verify the exact current offer and frame/foundation stack. See the PurpleRenew source assessment.

A maximum-height answer filters one mattress plan, not the full bed stack. Earlier PurpleFlex and New PurpleFlex each list an 8-inch profile, so they clear an inclusive ceiling of 8 inches or higher but not a 7- or 7.5-inch cap; the earlier Purple Mattress at 9.25 inches first fits at the allowed 9.5-inch ceiling. New Purple Mattress and New PurplePlus remain out of strict height matching because Purple publishes conflicting profile values for those entries. Earlier PurplePlus at 11 inches and Restore at 11.5 inches enter at their listed heights. Four distinct 13-inch plans—direct RestorePlus, RestorePlus Cool Touch and the two RestorePremier versions—plus Solaire enter at 13. Current Rejuvenate adds another Purple plan at exactly 14.5 inches; it first qualifies at that inclusive maximum, while Rx at 15 and HD at 15.5 enter later. RejuvenatePlus and current RejuvenatePremier enter at the product-page 15.5-inch boundary; the RejuvenatePremier is 15.5 inches, while Purple Support's dimension table gives the separate RejuvenatePlus a conflicting 16.5-inch value. Confirm RejuvenatePlus's discrepancy before close-clearance use. The separate Restore Cool Touch item is omitted from hard height matching: its size data says 11.5 inches while Purple's same-page build panel says 13, so one profile is not verified.

At 10 inches, PurpleFlex joins Zenhaven and Youth; all five 13-inch plans remain above the ceiling. At 11.5 inches, PurplePlus and Restore join the eligible set; at 12, Latex Hybrid joins; at 12.5, Contour5 joins. A 13-inch ceiling admits those five plans. At 14.5, current Rejuvenate and the Classic's taller plan are eligible; 15 adds Rx, and 15.5 adds HD and the separate RejuvenatePlus PDP plan. RejuvenatePlus's dimension-table discrepancy remains unresolved. Youth's two faces are both 10 inches, but its age-specific labels and Twin, Twin XL and Full sizes matter. Base compatibility is separate, and mattress height is not floor-to-surface height.

Purple's four separate Royale model pages report 15 inches for Duke, 16 for Duchess, and 17 for both Monarch and Crown; Mattress Firm's FAQ instead says 14.25 inches for each. These are product-page specifications, not independent measurements: verify the delivered profile if clearance is close. Duke, Duchess, Monarch and Crown remain distinct plans and constructions. The separate 2023 Rejuvenate support page lists 15.5 inches, but no exact current offer or size code was verified; its historical reference is not a finder result. The 2023 RejuvenatePlus and RejuvenatePremier tables list 16.5 inches, but those exact-generation models remain reference-only, not matches. Current RejuvenateUltimate at 17.5 inches now meets the valid 17.5-inch maximum boundary. Read the exact-profile RejuvenateUltimate assessment, the 2023 Rejuvenate version reference, the 2023 RejuvenatePlus review or the 2023 RejuvenatePremier review.

Open the finder to enter your actual height limit. Measure the entire support stack before treating a number as a room-clearance limit.

For the new Novaform group, a 10-inch maximum keeps SoFresh Plus; 12 inches also admits the Firm Advanced Back Support Plus; a 13.5-inch ceiling still excludes the 14-inch families. At 14 inches, the all-foam ComfortGrande Advanced, separate ComfortGrande hybrid and Serafina plans enter. These are page-listed mattress profiles, not bed-stack heights. 10-inch ceiling, 12-inch ceiling, 13.5-inch ceiling and 14-inch ceiling are different inclusive searches.

Maximum 10 inches

Neither the 12-inch BR800 Medium nor the maker-listed 11.75-inch Silver BRS900 Medium Firm fits this ceiling. The retailer's rounded 12-inch title for BRS900 does not make it a 10-inch plan.

Cloud One and The One each have an 11-inch profile, so both exceed this cap; the separate 10.5-inch answer records the half-inch boundary. Read the Cloud One and The One assessments.

Decision: A 10-inch maximum matches seven reviewed families, including PurpleFlex at 8 inches, The Purple Mattress at 9.25 inches, Zenhaven and Youth at 10 inches, Murphy Bed Mattress at 10 inches, Bunk & Trundle at 7 inches, and Soothing Nights through its 7-, 8- and 10-inch profiles. Its 12-, 14- and 16-inch plans are above this ceiling; PurplePlus at 11 inches and taller plans also exceed it. Restore Cool Touch is not scored because the exact Purple page conflicts between 11.5- and 13-inch height descriptions.

This is mattress thickness, not finished bed height. Youth is offered in Twin, Twin XL and Full with two age-designated faces; if 10 inches is a headboard or clearance limit, add the frame or foundation separately before deciding the setup fits.

RejuvenateUltimate's exact 17.5-inch mattress profile exceeds this 10-inch ceiling and is excluded; see the RejuvenateUltimate assessment.

Open the finder with a 10-inch maximum. Compare the PurpleFlex, excluded 13-inch RestorePlus Cool Touch and RestorePremier, the height-conflicted Restore Cool Touch, Zenhaven and Youth assessment.

The 10-inch maximum also admits Murphy Bed Mattress exactly; the 7-inch Bunk & Trundle profile is below every permitted maximum. Check the frame-specific Murphy and bunk/trundle assessments.

Novaform boundary check: Its exact 10-inch plan fits this ceiling; 12- and 14-inch new Novaform plans do not. See the individual SoFresh Plus assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Soothing Nights' exact profile list is 7, 8, 10, 12, 14 and 16 inches. The expanded slider reaches its 7-inch lower boundary, and each family result appears when at least one documented plan fits. Verify the selected SKU in the Soothing Nights review; compare the same-condition 7-inch ceiling and 8-inch ceiling answers.

Maximum 11.5 inches

Both the 12-inch BR800 Medium and maker-listed 11.75-inch Silver BRS900 Medium Firm exceed this maximum. Costco rounds the latter's title to 12 inches; the match uses the exact maker profile, which also remains above 11.5.

Decision: At an 11.5-inch maximum, Dream, Snow, both 12-inch Costco Cooling Select models, the 12-inch BR800 and Level Two Hybrid, and maker-listed 11.75-inch BRS900 are excluded; the 11-inch Casper The One and Cloud One and Soothing Nights' 7-, 8- and 10-inch profiles remain under the ceiling, while taller Purple/Saatva profiles follow their listed boundaries.

The exact Costco foam and hybrid listings both state a 12-inch mattress profile, so neither fits this ceiling; the foam/hybrid identity and comfort-label distinction is preserved in the foam and hybrid reviews.

The 10-inch Murphy and 7-inch Bunk & Trundle profiles also remain under the ceiling. Direct RestorePlus, RestorePlus Cool Touch and both distinct RestorePremier versions at 13 inches do not qualify. Restore Cool Touch remains unknown because its exact page conflicts on total height. Compare the separate Dream and Snow assessments before relying on a tight clearance.

This ceiling includes Casper Cloud One and The One at 11 inches, Classic's 11.5-inch plan but not its 14.5-inch plan, Memory Foam Hybrid's only height, Zenhaven's 10-inch plan, Youth's two 10-inch faces and Soothing Nights' 7-, 8- and 10-inch profiles. Add exact feel, size or base requirements only if they are also essential.

RejuvenateUltimate's exact 17.5-inch profile exceeds this 11.5-inch maximum and is excluded; compare its current assessment.

Open the finder with an 11.5-inch maximum. Compare Casper's Cloud One and The One with PurpleFlex, PurplePlus, excluded RestorePlus Cool Touch and RestorePremier, the unresolved Restore Cool Touch height report, Youth, Zenhaven and Classic.

Novaform boundary check: The 10-inch SoFresh plan fits; taller new Novaform profiles do not yet enter. See the individual SoFresh Plus assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Soothing Nights also qualifies because its 7-, 8- and 10-inch profiles are under this cap; its 12-, 14- and 16-inch options are not. The family result means that one or more of its plans fit; it does not claim that a particular size/profile is selected. Read the exact-profile assessment.

Maximum 12 inches

The 12-inch BR800 Medium enters exactly at this ceiling; the distinct 11.75-inch BRS900 Medium Firm also fits. Costco rounds the BRS900 title/profile to 12, but the maker's precise value is retained.

Decision: A 12-inch maximum admits Casper Dream and Snow, both distinct Costco Cooling Select 12-inch models, Beautyrest BR800 and the Level Two Hybrid at 12 inches, and BRS900 at its maker-listed 11.75 inches, alongside shorter plans; listed height is the mattress profile, not total bed elevation.

Dream Weaver Hybrid also fits through its 11.5-inch Medium plan, while its separate 12.5-inch Plush profile exceeds this ceiling. See the configuration review; its exact 12-inch finder answer is a mattress-only ceiling.

Soothing Nights also fits at its 7-, 8-, 10- and exact 12-inch profiles, including the listed 12-inch Firm plan; its 14- and 16-inch plans exceed this ceiling. The family match does not mean every profile fits. See the plan-by-plan review.

The exact Costco foam and hybrid selector pages both list a 12-inch plan, so each enters at this inclusive ceiling. The foam page calls its feel Medium; the hybrid's title and specification table disagree on Medium Firm versus Medium, a separate uncertainty that does not change the numeric boundary. See the foam review and hybrid review.

The inclusive 12-inch limit also admits PurpleFlex, The Purple Mattress, PurplePlus, standard Restore Hybrid, the 12-inch Latex Hybrid, Youth, Zenhaven, Classic and Memory Foam Hybrid. Direct RestorePlus, RestorePlus Cool Touch and both RestorePremier editions at 13 inches remain above it. Restore Cool Touch stays unscored because Purple's exact page gives conflicting 11.5- and 13-inch total-height descriptions. Review the distinct Dream and Snow plans; their same numeric profile does not mean identical construction.

This threshold excludes the 12.5-inch Contour5 and taller Rx and HD plans. It is a mattress-only ceiling; foundation and frame height still need a separate measurement.

RejuvenateUltimate is also excluded: Purple lists its mattress at 17.5 inches, above this 12-inch ceiling. See the exact-model assessment.

Open the finder with a 12-inch maximum. Compare PurpleFlex, PurplePlus, excluded 13-inch RestorePlus Cool Touch and RestorePremier, the unresolved Restore Cool Touch height report, Youth and Latex Hybrid.

Novaform boundary check: The 10-inch SoFresh and exact 12-inch Back Support plan fit; the new 14-inch families remain above this ceiling. See the individual SoFresh Plus; Advanced Back Support Plus assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum 12.5 inches

Decision: A 12.5-inch ceiling returns PurpleFlex, The Purple Mattress, PurplePlus, standard Restore Hybrid, Youth, Zenhaven, Classic, Latex Hybrid, Memory Foam Hybrid and Contour5; direct RestorePlus, RestorePlus Cool Touch, both RestorePremier versions and Solaire at 13 inches remain above the limit. Restore Cool Touch is excluded from hard height matching because its same-page total-height claims conflict.

Both Dream Weaver Hybrid profiles now fit at this inclusive edge: the 11.5-inch Medium and 12.5-inch Plush are separate plans, with only the latter exactly on the boundary. Read the exact-profile review and open this same 12.5-inch maximum search.

Soothing Nights' 7-, 8-, 10- and 12-inch profiles also fit; its 14- and 16-inch plans do not. Read its exact-profile review before treating a family match as an exact configuration.

Contour5's 12.5-inch height is the exact outer edge for that model; compare its all-foam Medium with the separate Memory Foam Hybrid rather than assuming construction follows the shared Medium label.

The 17.5-inch RejuvenateUltimate exceeds this 12.5-inch maximum and is not a match; see the reviewed Purple profile.

Both Costco Cooling Select plans are 12 inches and therefore also fit the 12.5-inch ceiling; they first enter at 12 inches. Compare the separate all-foam listing and foam-and-coil listing.

Open the finder with a 12.5-inch maximum. Compare PurpleFlex, PurplePlus, excluded 13-inch RestorePlus Cool Touch, RestorePremier, unresolved Restore Cool Touch, Youth, Zenhaven and Contour5.

Novaform boundary check: The 10-inch SoFresh and exact 12-inch Back Support plan fit; the new 14-inch families remain above this ceiling. See the individual SoFresh Plus; Advanced Back Support Plus assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum 13 inches

Decision: A 13-inch maximum includes direct RestorePlus, RestorePlus Cool Touch, both separate RestorePremier versions and Solaire at their listed 13-inch profiles; these join four shorter height-documented Purple plans and six shorter Saatva plans for a fifteen-family result. Novaform's 14-inch Legacy Premier Support Medium and Firm plans exceed this ceiling. The exact Mattress Firm RestorePlus Cool Touch pages both list the 13-inch profile. The separate Restore Cool Touch remains excluded because its exact Purple page conflicts between 11.5- and 13-inch total-height claims, so the matcher does not choose one.

The Solaire is not one fixed feel: Saatva describes an adjustable air-chamber range, and the page lists 13 inches. Confirm the exact size configuration and whether a Split or Upper-Flex base requirement applies.

The two Costco Cooling Select models also remain under this ceiling at their 12-inch mattress-only profiles. Their retailer sizes and model-specific limits are in the foam and hybrid assessments.

Novaform's exact Medium and Firm Legacy Premier Support pages each list a 14-inch mattress profile, so both exceed a 13-inch ceiling and first enter at 14. Read the model assessment and check a strict clearance against the exact selected plan.

RejuvenateUltimate's 17.5-inch mattress profile remains above this 13-inch ceiling; it is excluded. Read the exact-model assessment.

Open the finder with a 13-inch maximum. Compare direct RestorePlus, RestorePlus Cool Touch, direct RestorePremier and the separate RestorePremier Cool Touch with PurpleFlex, PurplePlus, Youth and the Solaire assessment.

Novaform boundary check: The 10-inch SoFresh and exact 12-inch Back Support plan fit; the new 14-inch families remain above this ceiling. See the individual SoFresh Plus; Advanced Back Support Plus assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum 14 inches

Decision: At a 14-inch maximum, 36 reviewed plans remain. Both Dream Weaver families have listed profiles below the ceiling, including the Hybrid's 11.5-inch Medium and 12.5-inch Plush plans. Within Novaform, the 10-inch SoFresh, 12-inch Back Support Plus, three new 14-inch ComfortGrande/Serafina families and the two Legacy Premier Support feel plans fit; the 16.5-inch Platinum remains above the ceiling. All values are mattress-only.

Casper lists both Max hybrids at 14 inches, but their Medium Soft feel package differs: Dream Max is described as responsive/lively, while Snow Max adds Casper's Snow Technology claims. Neither page provides an independent measurement, and a mattress-only profile excludes the base and frame.

Novaform's exact Medium and Firm Legacy Premier Support pages each list a 14-inch mattress profile and Full/Queen/King sizes. The separate feel-page descriptions differ; no numeric firmness score or named adjustable-base approval is published. See the Novaform assessment and verify exact delivered height for close clearance.

Open the finder with a 14-inch maximum. Compare the Dream Max and Snow Max assessments with the Novaform plan and taller Duke; measure the total assembled setup separately.

Novaform boundary check: All five new buying-eligible Novaform families fit this ceiling: SoFresh is 10 inches, Back Support Plus is 12, and the three other new families are 14 inches. See the individual SoFresh Plus; Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum 14.5 inches

Decision: At 14.5 inches, current Rejuvenate’s plan joins shorter Purple models and the Saatva height group. Murphy Bed Mattress at 10 inches and Bunk & Trundle at 7 inches add two exact Saatva profiles to the seven other plans at or below 13 inches; the products retain their separate intended frames. Restore Cool Touch remains unscored because its own Purple page disagrees on total height.

The higher ceiling does not add Rx at 15 inches or HD at 15.5 inches. It does not force the Classic onto a 14.5-inch plan; without a minimum, its 11.5-inch adjustable-base-compatible plan can satisfy the maximum.

RejuvenateUltimate is not included at this ceiling: its maker-listed 17.5-inch profile is higher than 14.5 inches. See the product assessment.

Open the finder with a 14.5-inch maximum. Compare the matching current Rejuvenate 14.5-inch plan with direct RestorePlus, RestorePlus Cool Touch, direct RestorePremier and RestorePremier Cool Touch, and with PurpleFlex, PurplePlus, Youth, Classic and Contour5.

Novaform boundary check: All five new buying-eligible Novaform families fit this ceiling: SoFresh is 10 inches, Back Support Plus is 12, and the three other new families are 14 inches. See the individual SoFresh Plus; Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum 15 inches

Decision: A 15-inch ceiling keeps the listed 15-inch Duke at the inclusive boundary, current Rejuvenate at 14.5 inches, the shorter resolved Purple plans and the Saatva Rx plan; it still excludes the 15.5-inch HD and the taller Royale Duchess (16 inches), Monarch and Crown (17 inches), and RejuvenateUltimate (17.5 inches). Solaire and Youth remain within the limit. The separate Restore Cool Touch is not counted because its Purple page conflicts between 11.5 and 13 inches.

At this threshold Youth, Zenhaven, Classic, Contour5, Latex Hybrid, Memory Foam Hybrid, Solaire and Rx remain. Confirm frame, base and total height separately; the height filter does not select a feel or establish comfort.

Open the finder with a 15-inch maximum. Compare the matching Duke at its listed 15-inch boundary and Rejuvenate 14.5-inch plan with the taller Duchess, Monarch and Crown. Also compare direct RestorePlus, RestorePlus Cool Touch, direct RestorePremier, RestorePremier Cool Touch, PurpleFlex, PurplePlus, Youth, Rx and HD.

Novaform boundary check: All five new buying-eligible Novaform families fit this ceiling: SoFresh is 10 inches, Back Support Plus is 12, and the three other new families are 14 inches. See the individual SoFresh Plus; Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum 15.5 inches

Decision: The current matcher returns 42 reviewed product entries at a 15.5-inch maximum. Both Dream Weaver families fit this ceiling, along with Duke at 15 inches and the PDP-listed 15.5-inch HD, RejuvenatePlus and RejuvenatePremier. Legacy Elite Premier at 16 inches, Duchess at 16, Monarch and Crown at 17, and RejuvenateUltimate at 17.5 do not. Purple Support gives RejuvenatePlus a conflicting 16.5-inch value, so confirm the exact delivered version if clearance is close; the separate Restore Cool Touch remains outside strict matching because its height claims conflict.

That includes a relatively tall mattress, not a 15.5-inch finished bed: add foundation, adjustable base and frame before checking access or headboard clearance.

Novaform's Legacy Elite Premier is listed at 16 inches, so it also falls outside this 15.5-inch cap; the exact 16-inch boundary admits it. RejuvenateUltimate's 17.5-inch profile is above this ceiling as well. Purple's separate 2023 Rejuvenate page lists 15.5 inches, but no current exact offer or size code is confirmed, so that generation is a historical reference, not a match. Read the Legacy Elite Premier, current RejuvenateUltimate or 2023 version assessment.

Open the finder with a 15.5-inch maximum. Compare matching Duke and RejuvenatePremier with the excluded taller Duchess, Monarch and Crown. Also compare RejuvenatePlus and its conflicting profile, matching Rejuvenate at 14.5 inches, direct RestorePlus, RestorePlus Cool Touch, direct RestorePremier, RestorePremier Cool Touch, PurplePlus and PurpleFlex, alongside the HD assessment.

Novaform boundary check: All five new buying-eligible Novaform families fit this ceiling: SoFresh is 10 inches, Back Support Plus is 12, and the three other new families are 14 inches. See the individual SoFresh Plus; Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum 16 inches

Decision: At the inclusive 16-inch ceiling, Novaform Legacy Elite Premier and Purple Duchess both meet their exact 16-inch profiles, and Duke at 15 inches is shorter; Novaform Platinum at 16.5 inches, the 17-inch Monarch and Crown and 17.5-inch RejuvenateUltimate remain above it. Mattress Firm's FAQ reports 14.25 inches for each Royale variant, conflicting with Purple's individual product-page heights, so verify the delivered profile if clearance is close.

This boundary admits the 16-inch Legacy Elite Premier Medium Firm plan and Duchess but not the 17-inch sister models; it is mattress thickness, not the height of the complete bed stack. Do not infer a different model's profile from the Royale family name.

Open the finder with a 16-inch maximum. Compare eligible Legacy Elite Premier, Duke and Duchess with excluded Novaform Platinum at 16.5 inches, Monarch, Crown and RejuvenateUltimate.

Novaform boundary check: All five new buying-eligible Novaform families fit this ceiling: SoFresh is 10 inches, Back Support Plus is 12, and the three other new families are 14 inches. See the individual SoFresh Plus; Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum 16.5 inches

Decision: A 16.5-inch maximum admits Novaform Legacy Elite Premier at 16 inches and the separate Platinum Medium plan at its exact 16.5-inch boundary; a 16-inch maximum excludes Platinum, while 17-inch Monarch and Crown and 17.5-inch RejuvenateUltimate remain above. Purple's separate 2023 RejuvenatePlus and RejuvenatePremier support tables list 16.5 inches, but those historical editions lack verified current offers and size codes and are not finder matches. Check the current RejuvenatePlus product-page/Support height discrepancy before relying on close clearance.

Novaform's separate product pages list Legacy Elite Premier as a 16-inch Medium Firm plan and Platinum as a 16.5-inch Medium plan, each with Queen and King. The exact reviews keep mattress-only thickness separate from the full bed stack and document their distinct listed weights.

Open the finder with a 16.5-inch maximum. Compare current Legacy Elite Premier at 16 inches and Platinum at its exact inclusive boundary with Duke and Duchess under the ceiling and the excluded taller Monarch and Crown; keep the old 2023 RejuvenatePlus and 2023 RejuvenatePremier support records distinct from current offers.

Novaform boundary check: All five new buying-eligible Novaform families fit this ceiling: SoFresh is 10 inches, Back Support Plus is 12, and the three other new families are 14 inches. See the individual SoFresh Plus; Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum 17 inches

Decision: A 17-inch maximum retains Novaform's 16-inch Legacy Elite Premier and 16.5-inch Platinum, adds both separate 17-inch Royale profiles—Purple Medium Monarch and Purple Plush Crown—and includes the 15-inch Duke and 16-inch Duchess; the 17.5-inch RejuvenateUltimate still exceeds this ceiling. Crown's Plush description is not the questionnaire's Plush Soft comfort option, and its Split King offer is a two-Twin-XL set according to the retailer selector.

Purple's four individual product pages report 15, 16 or 17 inches, while Mattress Firm's FAQ says 14.25 inches for each; these are conflicting published specifications, not independent measurements. Check the exact seller's current selectable item and support requirements where clearance matters.

Open the finder with a 17-inch maximum. Compare 16-inch Legacy Elite Premier and 16.5-inch Novaform Platinum with Duke, Duchess, Monarch and Crown, then the taller excluded RejuvenateUltimate.

Novaform boundary check: All five new buying-eligible Novaform families fit this ceiling: SoFresh is 10 inches, Back Support Plus is 12, and the three other new families are 14 inches. See the individual SoFresh Plus; Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum 17.5 inches

Decision: At the inclusive 17.5-inch maximum, the 16-inch Novaform Legacy Elite Premier and 16.5-inch Platinum remain below the ceiling, as do Duke at 15 inches, Duchess at 16, and Monarch and Crown at 17; RejuvenateUltimate meets the ceiling at 17.5 inches. This is the questionnaire's upper height bound, not a statement about final bed elevation or fit in a particular room.

For close clearance, Purple's model pages and Mattress Firm's 14.25-inch Royale FAQ disagree; the RejuvenateUltimate review describes its exact Purple-listed profile separately. Add the base and frame height before treating any mattress number as the whole setup.

Open the finder with a 17.5-inch maximum. Compare Novaform Legacy Elite Premier at 16 inches, Platinum at 16.5 inches and RejuvenateUltimate with the four distinct Duke, Duchess, Monarch and Crown assessments.

Novaform boundary check: All five new buying-eligible Novaform families fit this ceiling: SoFresh is 10 inches, Back Support Plus is 12, and the three other new families are 14 inches. See the individual SoFresh Plus; Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Minimum mattress height

Decision: At a 10-inch minimum, all five new purchasing Novaform families fit the inclusive floor; 11 inches removes the 10-inch SoFresh, 12.5 inches removes the 12-inch Back Support Plus, and 14.5 inches excludes the new 14-inch ComfortGrande/Serafina plans. Beautyrest's 11.75-inch BRS900 clears 11.5 but not 12; the 12-inch BR800 and Level Two Hybrid clear 11.5 and 12 but not 12.5. The Black Series One–Four pages publish no numeric mattress height, so they cannot be treated as meeting a height minimum. See the Level Two Hybrid, Series One, Series Two, Series Three and Series Four assessments; documented profiles are mattress-only.

Dream Weaver Hybrid's 11.5-inch Medium and 12.5-inch Plush both meet a 10- or 11-inch floor and clear 11.5; only the Plush meets a 12- or 12.5-inch floor, and neither reaches 13. These exact mattress-only boundaries do not predict finished-bed height. See the review and the same-condition 11.5-inch, 12.5-inch and 13-inch minimum searches.

Minimum-height answers cover 7 through 17.5 inches in half-inch steps. The 7-inch Bunk & Trundle Mattress meets the lower boundary. Purple's New PurpleFlex is listed at 8 inches, so it clears an 8-inch floor but not an 8.5-inch floor; this is a separate 2027 edition from earlier PurpleFlex. Murphy Bed Mattress is exactly 10 inches. Dream and Snow enter at a minimum of 12 inches, while the Dream Max and Snow Max meet the 14-inch boundary. These listed mattress heights do not include a base or frame. The New Purple Mattress and New PurplePlus have conflicting source heights and remain out of hard height matches; PurpleRenew's 11/11.5-inch disagreement remains unresolved too.

Decision: An inclusive 7-inch minimum admits the listed 7-inch Bunk & Trundle plan; at the next 7.5-inch floor that plan drops out, although Soothing Nights remains because it has an 8-inch plan.

Compare the exact 7-inch minimum with 7.5 inches. The Bunk & Trundle assessment is a 7-inch example, while Soothing Nights retains a qualifying 8-inch plan at the higher floor.

Decision: The New PurpleFlex entry lists an 8-inch profile; it meets an 8-inch minimum but falls below an 8.5-inch minimum. Its maker-listed height is not an independent measurement of the finished bed.

Compare the same-condition 8-inch minimum and 8.5-inch minimum. The New PurpleFlex meets the first; the separate Soothing Nights has a documented 10-inch plan at either floor. Add base and frame height separately.

Cloud One's 11-inch profile therefore fits the minimum-height choices at 10 and 11, but not 11.5 or above. Review the exact Cloud One size and profile record; base height is separate.

Novaform lists its separate Legacy Premier Support Medium and Firm plans at 14 inches. Both clear a minimum through 14 inches and fall below a stricter 14.5-inch floor; this does not establish base compatibility or total-bed height. Read the model review.

The separate Novaform Legacy Elite Premier is a 16-inch Medium Firm plan in Queen or King. It clears a 15.5- or 16-inch minimum, but falls below 16.5 inches and higher; at a 16.5-inch floor, the distinct Platinum is taller and remains eligible. Read the exact model review and remember that a minimum is not a maximum.

The two Costco Cooling Select models are each listed at 12 inches: both pass a 10-, 11-, 11.5- or 12-inch minimum, but neither meets 12.5 inches or any higher floor. The foam page labels its plan Medium; the distinct hybrid page's comfort-label conflict remains unresolved. Read the exact foam and hybrid records rather than treating a minimum as a maximum.

PurpleRenew is deliberately not counted inside or outside any strict height window. Its exact page’s table and profile label say 11 inches, while separate card data says 11.5 inches; until Purple clarifies which applies, the finder leaves its plan height unknown. Verify the exact current offer and frame/foundation stack. See the PurpleRenew source assessment.

The minimum-height finder begins at 7 inches. Earlier PurpleFlex is 8 inches and the earlier Purple Mattress is 9.25 inches, so they clear an 8-inch floor but not a 9.5-inch floor; PurplePlus at 11 inches and standard Restore at 11.5 inches enter at their listed heights. New PurpleFlex is a separate 8-inch entry. The New Purple Mattress and New PurplePlus have source conflicts and remain unknown for height matching. Four Purple plans plus Solaire at 13 inches enter at 10 and remain only through their documented heights; current Rejuvenate enters at 14.5 inches, and RejuvenatePlus and RejuvenatePremier qualify at 15.5 inches. Purple Support's dimension table gives the separate RejuvenatePlus a conflicting 16.5-inch value, so verify that height before relying on close clearance; RejuvenatePremier's exact current product page states 15.5 inches. The nine Saatva families span from 7 to 15.5 inches. The separate Restore Cool Touch model has conflicting same-page 11.5- and 13-inch total-height claims, so it is not counted as shorter or taller in any hard minimum-height answer.

At a 10-inch minimum, PurplePlus, Restore, direct RestorePlus, RestorePlus Cool Touch, both RestorePremier versions and current Rejuvenate join the qualifying set; PurpleFlex and The Purple Mattress fall short. At 11.5, PurplePlus and the 10-inch Youth and Zenhaven fall below, while Restore meets the threshold and the four 13-inch Purple plans plus Rejuvenate remain eligible. At 12, Restore and Memory Foam Hybrid drop out; at 12.5, Latex Hybrid drops out. At 13, Contour5 falls below while all four 13-inch Purple models, Rejuvenate and Solaire meet the boundary; at 13.5 the four 13-inch Purple plans fall short but Rejuvenate remains above the minimum. At 15, Rejuvenate falls below with the other shorter profiles; RejuvenatePlus and RejuvenatePremier are still above at their PDP-listed 15.5-inch values. At 15.5, HD, RejuvenatePlus and RejuvenatePremier match under the recorded plan heights, subject to the separate RejuvenatePlus Support-table conflict. The separate Restore Cool Touch remains unclassified because its published height statements conflict. An exact height window must fit one operating plan.

Duke at 15 inches, Duchess at 16, and Monarch and Crown at 17 are separate current plan profiles. Purple's page values conflict with Mattress Firm's 14.25-inch FAQ, so verify exact delivered height for close clearance. A 17.5-inch minimum leaves only a plan whose Purple profile reaches that height; see the specific Duke, Duchess, Monarch and Crown evidence rather than treating shared labels as shared heights. Current RejuvenateUltimate's exact 17.5-inch product-page profile meets every valid minimum through 17.5, but a minimum does not impose an upper limit; see the tall-model assessment. Purple's 2023 Rejuvenate support table records 15.5 inches, while separate 2023 RejuvenatePlus and RejuvenatePremier tables list 16.5 inches; the three old versions have no verified current offer or size code, remain reference-only and are excluded from finder results. Read the 2023 Rejuvenate reference, the 2023 RejuvenatePlus review or the 2023 RejuvenatePremier review.

Open the finder to enter your actual minimum. Mattress thickness is not bed clearance or required adjustable-base travel.

For the new group, a 10-inch floor includes SoFresh Plus, Back Support Plus and all three 14-inch families; 11 or 12 inches keeps the 12-inch and 14-inch plans but not SoFresh. A 12.5-inch floor leaves only the three 14-inch groups, while 14 retains them and 14.5 removes them. 10-inch minimum, 11-inch minimum, 12.5-inch minimum, 14-inch minimum and 14.5-inch minimum are separate inclusive scenarios. Add the base/frame separately.

Firm, back, Queen and an exact height window

Decision: With Firm, back-sleeper guidance, Queen, adjustable-base use and an 8-inch minimum/maximum window held together, the earlier and New PurpleFlex entries qualify; the two New Purple height-conflicted entries do not pass the numeric window.

Run the exact Firm/back/Queen/base and 8-inch window. Compare the separate earlier PurpleFlex and New PurpleFlex assessments; the New Purple Mattress and New PurplePlus source height conflicts are not assigned a numeric match.

Minimum 10 inches

Both the BR800 Medium at 12 inches and Silver BRS900 Medium Firm at 11.75 inches clear this minimum. Costco rounds the BRS900 title to 12; the maker's exact profile remains below the next 12-inch floor.

Casper Cloud One's 11-inch plan also clears this inclusive floor; verify the exact size and the full frame stack in the Cloud One review.

Decision: A 10-inch minimum returns 46 reviewed families. Both Dream Weaver families and Soothing Nights clear the inclusive floor; Soothing Nights' 10-, 12-, 14- and 16-inch profiles qualify, but its 7- and 8-inch profiles do not. The Hybrid's exact plans are 11.5-inch Medium and 12.5-inch Plush. The 12-inch BR800 and Level Two Hybrid, and 11.75-inch BRS900 also clear the floor, as do all five new buying-eligible Novaform families; taller plans remain eligible because this is a floor, not a ceiling.

Use the maximum separately if you need a range; mattress thickness is not final bed height. PurplePlus, Restore and RestorePlus clear this minimum at their listed heights, while PurpleFlex and The Purple Mattress do not. Novaform Platinum is listed at 16.5 inches and therefore clears the floor; its Queen variant is also unusually heavy at 173.5 pounds. RejuvenateUltimate also qualifies at 17.5 inches; a 10-inch minimum does not cap height. See the Platinum assessment and RejuvenateUltimate profile.

Both Costco Cooling Select plans also meet this 10-inch floor at their listed 12-inch profiles. Their exact item selectors and separate model limits are covered in the foam and hybrid reviews.

At this 10-inch floor, Soothing Nights' 10-, 12-, 14- and 16-inch plans qualify; its 7- and 8-inch plans fall below this threshold. Read the profile review and use the finder link below for the exact 10-inch condition.

Open the finder with a 10-inch minimum. Compare matching Rejuvenate at 14.5 inches and RejuvenatePlus at the PDP-listed 15.5 inches with PurplePlus, direct RestorePlus, RestorePlus Cool Touch, direct RestorePremier and RestorePremier Cool Touch, plus Youth and Zenhaven.

At the inclusive 10-inch minimum, Murphy Bed Mattress is exactly on the threshold; the 7-inch Bunk & Trundle falls below this threshold. See Murphy and Bunk & Trundle.

The inclusive 10-inch threshold is the current Murphy Bed Mattress’s exact profile, while Bunk & Trundle is 7 inches and does not pass. Check the dedicated Murphy and Bunk & Trundle reviews for frame-specific limits.

Novaform boundary check: All five new buying-eligible Novaform families clear this inclusive floor; the exact 10-, 12- and 14-inch profiles remain distinct. See the individual SoFresh Plus; Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Minimum 11.5 inches

Both Beautyrest profiles clear this inclusive floor: the BRS900 is 11.75 inches on its maker page and the BR800 is 12 inches. The Costco title rounds BRS900 to 12; use the manufacturer value for this boundary and verify the seller's selected configuration.

Decision: An 11.5-inch minimum excludes the 11-inch The One and Cloud One; Dream, Snow, the 12-inch BR800 and Level Two Hybrid, and maker-listed 11.75-inch BRS900 meet it. Both Dream Weaver Hybrid plans also clear this floor: Medium is exactly 11.5 and Plush is 12.5 inches. Soothing Nights qualifies through its 12-, 14- and 16-inch profiles, not its 10-inch or shorter plans; see the Hybrid review, Soothing Nights review and the same 11.5-inch finder condition.

At this inclusive floor, Restore meets the boundary exactly and direct RestorePlus, RestorePlus Cool Touch, both RestorePremier versions at 13 inches, current Rejuvenate at 14.5 inches, and RejuvenatePlus and RejuvenatePremier at the PDP-listed 15.5 inches also qualify, joining seven Saatva families. RejuvenatePlus's Support dimensions table instead says 16.5 inches, so verify that profile for close clearance. Restore Cool Touch remains excluded from the numeric answer because Purple's page gives both 11.5- and 13-inch overall-height statements. The separate Casper model evidence is in the The One, Cloud One, Dream and Snow assessments.

This boundary admits Restore and the taller RestorePlus, as well as a Classic 11.5-inch plan and Memory Foam Hybrid; Youth and Zenhaven are below it. Use another condition if you need an exact thickness or particular base.

For a documented 11.5-inch match, compare the Purple Restore Hybrid assessment; it has its own 11.5-inch manufacturer-listed plan.

At an 11.5-inch minimum, Casper Cloud One and The One both fall one half-inch short of the requested floor. See the Cloud One and The One profile assessments; do not round a manufacturer's mattress figure or add a foundation's height to meet this mattress-only minimum.

The two separate Costco Cooling Select products meet this 11.5-inch minimum at their exact 12-inch profiles. This is a height-only result: the foam plan is retailer-labeled Medium, while the hybrid's comfort label remains unresolved. See the foam and hybrid assessments.

Novaform's Platinum is 16.5 inches, so it clears a 10-inch floor but does not meet a higher 17-inch minimum. The separate Queen/King Medium plan is not an adjustable-base or full-bed-height claim; read the exact model assessment and measure the whole frame stack. The 17.5-inch RejuvenateUltimate also meets this 11.5-inch minimum; it is not a maximum-height match question. See the Purple assessment.

Open the finder with an 11.5-inch minimum. Compare matching Rejuvenate at 14.5 inches and RejuvenatePlus with direct RestorePlus, RestorePlus Cool Touch, direct RestorePremier and RestorePremier Cool Touch, Memory Foam Hybrid and Classic; read the excluded Youth assessment to check its 10-inch profile.

The new Saatva Murphy profile is 10 inches and Bunk & Trundle is 7 inches; neither passes this minimum. See the Murphy and Bunk & Trundle assessments for their separate setup restrictions.

Novaform boundary check: The exact 12-inch Back Support and 14-inch foam/hybrid/Serafina plans clear this floor; the 10-inch SoFresh does not. See the individual Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Minimum 12 inches

The BR800 Medium and the 12-inch Level Two Hybrid meet this inclusive floor. The distinct Silver BRS900 Medium Firm is 11.75 inches on the manufacturer page, even though Costco rounds its title/profile to 12.

Decision: A 12-inch minimum admits Casper Dream, Snow, Beautyrest BR800 and the Level Two Hybrid at their listed profiles; the 11.75-inch Silver BRS900 and 11-inch The One and Cloud One fall below it, while taller plans also qualify. Of the two Dream Weaver Hybrid plans, only 12.5-inch Plush meets this floor; its 11.5-inch Medium is below 12. Soothing Nights qualifies through its exact 12-, 14- and 16-inch plans, including the 12-inch Firm boundary; see the Hybrid review, Soothing Nights review and the same 12-inch minimum finder.

With Queen and Medium Firm held fixed, this exact 12-inch-floor search includes Level Two Hybrid. A 12.5-inch floor excludes it as well as BRS900 and BR800; compare the same conditions at the next boundary in the 12.5-inch search.

The 13-inch direct RestorePlus, RestorePlus Cool Touch and two RestorePremier versions, current 14.5-inch Rejuvenate, 15.5-inch PDP-listed RejuvenatePlus and RejuvenatePremier, and qualifying Saatva families also join the result. RejuvenatePlus's Support dimensions table instead lists 16.5 inches, so verify close-clearance dimensions. Restore Cool Touch does not pass a hard numeric height requirement because its size table and build panel conflict. See the distinct Casper Dream and Snow reviews; their profiles are maker-listed mattress thickness, not total-bed height.

The Classic remains because its 14.5-inch plan is still above the minimum; its lower 11.5-inch plan does not satisfy the selected bound. Youth has no taller listed face.

RejuvenateUltimate's documented 17.5-inch mattress also clears this 12-inch minimum; see its assessment.

Both Costco Cooling Select models also enter at this inclusive 12-inch minimum; their product pages list 12-inch mattress-only plans. Compare the foam model with the separate hybrid model, whose feel label is unresolved even though its height is known.

Open the finder with a 12-inch minimum. Compare matching current Rejuvenate and RejuvenatePlus with direct RestorePlus, RestorePlus Cool Touch, direct RestorePremier and RestorePremier Cool Touch, Latex Hybrid and Contour5.

The new Saatva Murphy profile is 10 inches and Bunk & Trundle is 7 inches; neither passes this minimum. See the Murphy and Bunk & Trundle assessments for their separate setup restrictions.

Novaform boundary check: The exact 12-inch Back Support and 14-inch foam/hybrid/Serafina plans clear this floor; the 10-inch SoFresh does not. See the individual Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Minimum 12.5 inches

Neither Beautyrest mattress clears this floor: the maker lists BRS900 at 11.75 inches and BR800 and the Level Two Hybrid at 12 inches. Costco rounds BRS900's title/profile to 12, still below 12.5. Read the separate BRS900 and BR800 reviews before treating the retailer's rounded description as a clearance measure.

Decision: A 12.5-inch minimum excludes the 12-inch Beautyrest BR800 and Level Two Hybrid and the maker-listed 11.75-inch Silver BRS900, while keeping direct RestorePlus, RestorePlus Cool Touch and both direct and Cool Touch RestorePremier versions, current Rejuvenate at 14.5 inches, RejuvenatePlus and RejuvenatePremier at the PDP-listed 15.5 inches, Classic, Contour5, HD, Rx and Solaire; height-documented shorter plans including PurpleFlex, PurplePlus, Restore, Youth, Zenhaven and Memory Foam Hybrid also fall below it. Dream Weaver Hybrid qualifies at this exact floor only through its 12.5-inch Plush plan; its 11.5-inch Medium does not clear 12.5 and Plush is not the finder's Plush Soft selector. See the plan-specific review and the same 12.5-inch finder condition. Purple Support's dimensions table instead lists RejuvenatePlus at 16.5 inches; verify if clearance is close. Restore Cool Touch remains unclassified for height rather than being presumed shorter.

Contour5 sits exactly on this boundary. The Classic remains only through its taller plan; this product-level result does not mean both Classic heights meet the same minimum.

Soothing Nights' 14- and 16-inch profiles meet this 12.5-inch floor; its 12-inch and shorter profiles do not. Its exact plan-level heights are listed in the review; the finder link above keeps this same minimum.

Holding Queen and Medium Firm constant, the 12.5-inch minimum excludes the Level Two Hybrid; its 12-inch mattress profile is not a measurement of the base or finished bed.

Both Costco Cooling Select profiles are 12 inches, so they fall one half-inch short of this 12.5-inch minimum. Compare their exact heights and distinct variants in the foam and hybrid reviews.

RejuvenateUltimate's exact 17.5-inch height is above the 12.5-inch minimum, so it qualifies for this minimum-only answer. Read the model review.

Open the finder with a 12.5-inch minimum. Compare matching current Rejuvenate and RejuvenatePlus with direct RestorePlus, RestorePlus Cool Touch, direct RestorePremier and RestorePremier Cool Touch, Contour5 and Classic.

The new Saatva Murphy profile is 10 inches and Bunk & Trundle is 7 inches; neither passes this minimum. See the Murphy and Bunk & Trundle assessments for their separate setup restrictions.

Novaform boundary check: Only the three 14-inch new Novaform families clear this floor; the 10-inch SoFresh and 12-inch Back Support are below it. See the individual ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Minimum 13 inches

Decision: A 13-inch minimum returns direct RestorePlus, RestorePlus Cool Touch, both distinct RestorePremier versions, current Rejuvenate at 14.5 inches, RejuvenatePlus and RejuvenatePremier at the PDP-listed 15.5 inches, Classic, HD, Rx and Solaire; the four Purple plans with an established 13-inch operating height meet the threshold exactly, while the height-documented shorter Purple plans and Youth fall below it. Neither Dream Weaver Hybrid profile meets 13 inches: its tallest maker-listed option is 12.5. See the review and the same 13-inch finder answer. Purple Support's dimensions table says RejuvenatePlus is 16.5 inches, so confirm the actual profile. The separate Restore Cool Touch source conflict prevents a reliable numeric match.

The Solaire maker lists a 13-inch height for its adjustable-firmness mattress. Check the specific size and base pairing, and remember that foundations and frames add to finished bed height.

Soothing Nights' 14- and 16-inch profiles also meet this 13-inch floor; its 12-inch and shorter plans do not. Check the exact profile in the review alongside this section's same-condition finder link.

At its maker-listed 17.5-inch profile, RejuvenateUltimate also meets a 13-inch minimum; see the exact product assessment.

Open the finder with a 13-inch minimum. Compare matching Rejuvenate at 14.5 inches, RejuvenatePlus and RejuvenatePremier at the PDP-listed 15.5 inches with direct RestorePlus, RestorePlus Cool Touch, direct RestorePremier and RestorePremier Cool Touch, Solaire and Classic.

The new Saatva Murphy profile is 10 inches and Bunk & Trundle is 7 inches; neither passes this minimum. See the Murphy and Bunk & Trundle assessments for their separate setup restrictions.

Novaform boundary check: Only the three 14-inch new Novaform families clear this floor; the 10-inch SoFresh and 12-inch Back Support are below it. See the individual ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Minimum 13.5 inches

Decision: Novaform's Medium and Firm Legacy Premier Support plans at 14 inches clear this 13.5-inch minimum; RejuvenateUltimate's 17.5-inch mattress also exceeds the floor, which does not imply either profile meets a height ceiling. See the model assessments.

This threshold also excludes the four Purple plans with documented 13-inch profiles—direct RestorePlus, RestorePlus Cool Touch and both RestorePremier versions—and Solaire, but retains 14.5-inch Rejuvenate, 15.5-inch PDP-listed RejuvenatePlus and RejuvenatePremier, Classic, HD and Rx; shorter confirmed plans fall below. Purple Support's table lists RejuvenatePlus at 16.5 inches, so confirm the conflicting profile. Restore Cool Touch is not classified below 13.5 inches because its sources conflict on overall height.

A model can offer a wide firmness range yet still fall below a true height requirement. Confirm whether your measurement is mattress-only or includes its support base.

RejuvenateUltimate's 17.5-inch mattress also exceeds this 13.5-inch minimum; that does not imply it meets any height ceiling. See the tall-plan review. Novaform's model assessment explains its separate 14-inch Medium and Firm plans.

Soothing Nights' 14- and 16-inch profiles clear 13.5 inches; its 12-inch and shorter options do not. See the profile review and use this section's finder link for the same floor.

Open the finder with a 13.5-inch minimum. Compare matching Novaform 14-inch plans and Rejuvenate at 14.5 inches with RejuvenatePlus, excluded direct RestorePlus, RestorePlus Cool Touch, direct RestorePremier and RestorePremier Cool Touch, alongside Solaire, qualifying Rx and Classic.

The new Saatva Murphy profile is 10 inches and Bunk & Trundle is 7 inches; neither passes this minimum. See the Murphy and Bunk & Trundle assessments for their separate setup restrictions.

Novaform boundary check: Only the three 14-inch new Novaform families clear this floor; the 10-inch SoFresh and 12-inch Back Support are below it. See the individual ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Minimum 14 inches

Decision: A 14-inch minimum includes both Casper Max families and Novaform's separate Medium and Firm Legacy Premier Support plans at their exact listed profiles; the separate 16.5-inch Platinum Queen/King plan is also above the floor. Profiles below 14 inches fall short, while taller documented profiles remain eligible because this is a minimum rather than a maximum.

Dream Max and Snow Max each have one 14-inch Medium Soft hybrid plan and list Split King, but their cover/cooling construction differs. Their heights come from Casper's product specifications and are not independent measurements or complete bed elevation. Check the foundation, adjustable frame and exact package separately.

Novaform's exact Medium and Firm Legacy Premier Support pages each list a 14-inch profile; a 14-inch floor admits both, while a 14.5-inch floor excludes them. Its separate Platinum Queen/King Medium plan is 16.5 inches and also clears this floor. The pages name different top/support-foam descriptions and do not establish a shared feel scale or a named adjustable-base approval. Read the Legacy assessment and Platinum review.

Soothing Nights' exact 14-inch plan meets this inclusive floor alongside its 16-inch profile; the 12-inch and shorter plans fall below it. Read the plan review and follow the 14-inch finder link in this answer.

Open the finder with a 14-inch minimum. Read the Dream Max and Snow Max assessments alongside the Novaform review, and compare the below-threshold 13-inch RestorePlus.

Novaform boundary check: Only the three 14-inch new Novaform families clear this floor; the 10-inch SoFresh and 12-inch Back Support are below it. See the individual ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Minimum 14.5 inches

Decision: A 14.5-inch minimum leaves current Rejuvenate, RejuvenatePlus, RejuvenatePremier, Classic, HD and Rx; Rejuvenate meets the boundary with its single 14.5-inch plan, RejuvenatePlus and RejuvenatePremier qualify on the PDP-listed 15.5-inch height, and Classic qualifies only through its 14.5-inch plan, while the other eight Purple plans with resolved heights are below. Purple Support's table instead lists RejuvenatePlus at 16.5 inches, so verify the profile for a tight clearance. Restore Cool Touch is not included as a below-threshold plan because its exact page conflicts on total height.

Youth, Zenhaven, Latex Hybrid, Contour5 and Memory Foam Hybrid are below this threshold. Check the exact Classic height rather than treating its family match as evidence that the 11.5-inch version qualifies.

At 14.5 inches, only Soothing Nights' 16-inch profile remains above the floor; the exact 14-inch plan no longer qualifies. Review the profile-level assessment and use the exact finder link in this section.

RejuvenateUltimate is also above this 14.5-inch minimum at its documented 17.5-inch profile; a minimum does not impose a ceiling. See the current-model review.

Open the finder with a 14.5-inch minimum. Compare Rejuvenate, RejuvenatePlus, RejuvenatePremier, Classic and HD.

The new Saatva Murphy profile is 10 inches and Bunk & Trundle is 7 inches; neither passes this minimum. See the Murphy and Bunk & Trundle assessments for their separate setup restrictions.

Minimum 15 inches

Decision: A 15-inch minimum admits the inclusive 15-inch Duke, Novaform's 16-inch Legacy Elite Premier, Duchess at 16 inches, Monarch and Crown at 17 inches, RejuvenateUltimate at 17.5 inches, RejuvenatePlus and RejuvenatePremier at their PDP-listed 15.5 inches, HD and Rx. Shorter resolved Purple plans, including the four distinct 13-inch RestorePlus/RestorePremier direct and Cool Touch editions, plus Youth, Zenhaven, Classic and Contour5, fall below 15 inches. Purple Support's dimensions table instead lists RejuvenatePlus at 16.5 inches, so verify the conflict. Restore Cool Touch's conflicting 11.5-/13-inch specifications keep it outside numeric matches rather than establish it below 15 inches.

The eligible models differ in feel, dimensions and setup. Confirm the actual selected height and full bed stack before deciding that a tall profile works.

Soothing Nights contributes only its 16-inch plan at this 15-inch floor; its 14-inch plan is below it. See its exact profile list and keep the floor separate from any maximum.

All four separate Royale profiles also meet this 15-inch floor: compare Duke, Duchess, Monarch and Crown with RejuvenateUltimate's documented profile without treating a minimum as a height limit.

Open the finder with a 15-inch minimum. Compare Novaform's qualifying 16-inch Legacy Elite Premier plan with RejuvenatePlus's PDP and Support profile discrepancy, Rx and HD.

Minimum 15.5 inches

Decision: A 15.5-inch minimum excludes Duke at 15 inches but admits Novaform Legacy Elite Premier at 16 inches, Duchess at 16 inches, Monarch and Crown at 17, RejuvenateUltimate at 17.5, HD, RejuvenatePlus and current RejuvenatePremier on their product-page heights. Purple Support's dimension table instead lists current RejuvenatePlus at 16.5 inches, so verify that separate conflict before close-clearance use. The other current/retail Purple models with resolved heights, Youth and the remaining reviewed plans are shorter; Restore Cool Touch remains unresolved rather than counted as shorter. The 2023 Rejuvenate support table also records 15.5 inches, but its current offer and SKU are unverified, so this reference-only edition does not appear in the finder.

This is a thick mattress plan; the number is not a promised final sleep-surface elevation. Verify the HD foundation/support, center support and all room clearances.

Soothing Nights' 16-inch profile clears 15.5 inches, but the 14-inch and lower profiles do not. See the review and this answer's exact 15.5-inch finder link.

RejuvenateUltimate's maker-listed 17.5-inch profile also clears this 15.5-inch minimum; it does not prove the bed fits beneath a 15.5-inch ceiling. See the exact model review. The separate 2023 Rejuvenate's 15.5-inch support-table height remains reference-only because no current exact offer or size code was confirmed, so it is not a finder match. Read the current model review or the 2023 version reference.

Open the finder with a 15.5-inch minimum. Compare qualifying 16-inch Legacy Elite Premier, Duchess, Monarch and Crown with excluded Duke, RejuvenatePremier's exact 15.5-inch profile, RejuvenatePlus's conflicting height references and the HD assessment.

Minimum 16 inches

Decision: A 16-inch minimum admits Novaform Legacy Elite Premier at its inclusive 16-inch profile, Platinum at 16.5 inches, Duchess at 16, both 17-inch Monarch and Crown, and 17.5-inch RejuvenateUltimate; the 15-inch Duke falls below this floor. These are separate models, and the Mattress Firm FAQ's 14.25-inch Royale figures conflict with Purple's individual product pages.

A minimum is not a maximum: it lets the taller profiles remain eligible and does not establish frame, base or room compatibility. Verify close-clearance dimensions against the exact delivered product.

Soothing Nights' 16-inch Plush Pillow Top reaches this inclusive threshold exactly; its next-tallest 14-inch profile does not. This is a family-level match through the exact 16-inch profile, not the Plush Soft matcher label. Read the plan-by-plan review and follow the same 16-inch finder link below.

Open the finder with a 16-inch minimum. Compare qualifying Novaform Legacy Elite Premier at the exact threshold, Platinum, Duchess, Monarch, Crown and RejuvenateUltimate with excluded Duke.

Minimum 16.5 inches

Decision: At the inclusive 16.5-inch minimum, Novaform's Platinum Queen/King Medium plan enters; Legacy Elite Premier at 16 inches, Duchess at 16 and Duke at 15 are below, while Monarch and Crown at 17 and RejuvenateUltimate at 17.5 remain above. The 2023 RejuvenatePlus and RejuvenatePremier support records also say 16.5 inches, but those historical versions remain outside the current matcher because exact current offers and size codes were not established.

Current RejuvenatePlus has a separate product-page/Support height discrepancy; the historical entries do not resolve it or authorize transferring their specifications. Check the right generation and full support stack before ordering.

Soothing Nights is excluded at this 16.5-inch minimum: its tallest exact page-listed profile is the 16-inch Plush Pillow Top, which is half an inch short. Its 7-, 8-, 10-, 12- and 14-inch options are shorter still. Read the source review; the finder link here is the exact same threshold.

Open the finder with a 16.5-inch minimum. Compare the Platinum plan at its exact 16.5-inch boundary with eligible Monarch, Crown and RejuvenateUltimate, plus below-threshold Legacy Elite Premier at 16 inches, Duchess and Duke; see the separate 2023 RejuvenatePlus and 2023 RejuvenatePremier historical reviews.

Minimum 17 inches

Decision: At the inclusive 17-inch minimum, Monarch and Crown meet their Purple-listed profiles, and the 17.5-inch RejuvenateUltimate also qualifies; Novaform Legacy Elite Premier at 16 inches, Platinum at 16.5, Duchess at 16 and Duke at 15 are below the threshold. Monarch and Crown share a listed height but not the same construction or Purple feel label.

Mattress Firm's FAQ instead reports 14.25 inches for all four Royale models. Confirm the exact version and actual clearance with the seller; this matcher uses the individual Purple product-page values and does not describe the bed's finished height.

Open the finder with a 17-inch minimum. Compare eligible Medium Monarch, Plush Crown and RejuvenateUltimate with shorter 16-inch Legacy Elite Premier, 16.5-inch Platinum, Duchess and Duke.

Minimum 17.5 inches

Decision: Only the exact 17.5-inch RejuvenateUltimate profile reaches the questionnaire's 17.5-inch minimum in the reviewed plans; Novaform Legacy Elite Premier at 16 inches, Duke at 15, Duchess at 16, and Monarch and Crown at 17 are below this floor. A minimum does not set an upper height limit.

Purple's product-page height is not an independent measurement, and the mattress height alone does not establish a suitable final bed elevation. Measure the frame and base stack, and check the exact seller's selectable item if a fraction of an inch matters.

Medium Firm Queen with an exact 16-inch window

Decision: When Medium Firm, Queen, and an inclusive 16-inch minimum and maximum are selected together, Novaform Legacy Elite Premier is the single reviewed match in this catalog.

The exact Novaform page lists that one plan at 16 inches and the Queen selector lists 60 × 80 × 16 inches. This is mattress-only height and does not establish an adjustable-base approval or total bed height; compare the source-based model assessment and verify the frame and delivery route.

Open the finder with Medium Firm, Queen and an exact 16-inch window.

The same Medium Firm Queen need with a 16.5-inch window

Decision: No reviewed plan in this library documents Medium Firm, Queen and an exact 16.5-inch mattress height; Legacy Elite Premier is listed at 16 inches and misses the minimum. This is a source-library gap, not proof that no such mattress exists elsewhere.

The 16.5-inch window is stricter than the selected model's stated profile; do not round it up or substitute Novaform Platinum, whose 16.5-inch plan is labelled Medium rather than Medium Firm. Read both exact assessments before deciding which constraint can change.

Open the finder with Medium Firm, Queen and an exact 16.5-inch window. Compare the 16-inch Legacy Elite Premier with the separate 16.5-inch Platinum plan.

Queen, 10-inch height, Firm side and adjustable base

Decision: Requiring Queen, an exact 10-inch height, a maker-described Firm face, stomach-sleeper guidance and adjustable-base compatibility selects Zenhaven only in this reviewed library; PurpleFlex at 8 inches and The Purple Mattress at 9.25 inches fail the exact-height and Firm-feel requirements.

The 10-inch requirement distinguishes Zenhaven from both shorter Purple profiles and the Classic's taller Firm plan. The Purple Mattress is Medium-Firm and its listed 9.25-inch profile is below the exact window; Zenhaven's matching feel is specifically its Gentle Firm reversible face, and its exact Split King or Upper-Flex bases are separate configurations not selected by this Queen answer.

Open the finder with all six Queen setup choices. Compare the PurpleFlex assessment and Purple Mattress with the Zenhaven assessment.

PurpleRenew is excluded from strict height windows because the maker page conflicts between 11- and 11.5-inch claims; its plan height remains unknown pending clarification. Read the source assessment before relying on a clearance threshold.

Exact 12.5-inch window with Queen Medium

Decision: A 12.5-inch minimum and maximum, Queen, Medium and adjustable-base requirement isolate the current Contour5 plan; the direct and retailer RestorePlus versions and both RestorePremier versions are listed at 13 inches and above this window.

The same criteria exclude the 11.5-inch Memory Foam Hybrid and other feel families. Direct RestorePlus is 13 inches and its Medium-soft description is distinct from Medium; the separate RestorePlus Cool Touch is also 13 inches, seller-labeled Medium, and does not fit this exact 12.5-inch ceiling. RestorePremier is 13 inches with unresolved feel-to-code identity. Restore Cool Touch is not counted as meeting this exact window because the product page's 11.5- and 13-inch height statements conflict. The exact height condition matters because family names alone do not identify a supported operating plan.

Open the finder with the exact Contour5 height window. Read Restore Cool Touch, the Contour5, direct RestorePlus, RestorePlus Cool Touch and RestorePremier assessments.

PurpleRenew is excluded from strict height windows because the maker page conflicts between 11- and 11.5-inch claims; its plan height remains unknown pending clarification. Read the source assessment before relying on a clearance threshold.

Exact 14.5-inch window

Decision: A 14.5-inch minimum and maximum yields Rejuvenate and the Classic family among models with a supported height at this exact boundary; Rejuvenate has one 14.5-inch plan, while Classic's qualifying plan is its taller 14.5-inch version. RestorePlus Cool Touch's listed 13-inch plan is below this exact window; Restore Cool Touch remains unresolved for this numeric condition.

The HD and Rx are taller than this exact window, while shorter profiles are below its minimum. If the window describes a room constraint, add the support stack separately instead of counting mattress thickness as total bed height.

RejuvenateUltimate's 17.5-inch mattress exceeds this 14.5-inch maximum, so the minimum and maximum cannot both be satisfied by that model. Read the current profile assessment.

Open the finder with an exact 14.5-inch window. Compare the Rejuvenate 14.5-inch plan and the qualifying Classic assessment with the excluded RestorePlus Cool Touch 13-inch profile and the height-conflicted Restore Cool Touch.

PurpleRenew is excluded from strict height windows because the maker page conflicts between 11- and 11.5-inch claims; its plan height remains unknown pending clarification. Read the source assessment before relying on a clearance threshold.

Minimum taller than maximum

Decision: A 15-inch minimum paired with a 14.5-inch maximum has no match because no documented mattress can meet both bounds simultaneously.

This is a real constraint conflict, not a product recommendation. Recheck the measurement and keep both limits in the finder if they are essential.

Open the finder with both incompatible height limits.

PurpleRenew is excluded from strict height windows because the maker page conflicts between 11- and 11.5-inch claims; its plan height remains unknown pending clarification. Read the source assessment before relying on a clearance threshold.

Split California King plus Firm

Decision: Split California King combined with the named Firm feel returns the Classic only in this reviewed library.

Confirm that your frame is a Split California King and that the Classic selector lists the exact height/feel combination at order time; do not assume every split package supports every frame or base.

Open the finder with Split California King and Firm selected. Read the Classic assessment.

Split King plus Medium

Decision: Split King plus Medium returns eight plans, including the distinct Casper Dream and Snow 12-inch hybrids, RejuvenatePlus, PurplePlus, standard Restore, Restore Cool Touch, Contour5 and Memory Foam Hybrid. Cloud One does not match this exact combination because Casper labels its plan Medium Soft; its named bundle still provides a separate Split King route.

Dream and Snow each offer Split King and a Medium 12-inch profile; Casper does not specify the split package pieces on either exact page, so verify whether the selected offer includes two Twin XL mattresses and the paired base. Compare the separate Dream and Snow reviews; their shared questionnaire labels do not establish equivalent construction or package contents.

These are different builds. RejuvenatePlus's current product page lists a Split King size and one Medium plan; Purple Support names two compatible Smart Base families but does not confirm the exact Split King pairing, and its profile conflicts between 15.5 and 16.5 inches. Purple's exact product page lists a Split King code for Restore Cool Touch, and Mattress Firm describes that item as two Twin XL mattresses; its conflicting 11.5-/13-inch overall-height statements are not converted into a numeric filter here. PurplePlus and standard Restore list two-piece Split Kings and conditional adjustable-base support; Restore's listed pair is two 80-by-38-inch pieces at 11.5 inches and 72 lb each. Direct RestorePlus also lists Split King, but its Medium-soft feel is distinct from the requested Medium. The separate RestorePlus Cool Touch page lists only Twin XL, Full, Queen, King and California King. Cloud One is another excluded plan here: its label is Medium Soft, not Medium, even though the current Adjustable Bundle separately lists two Twin XL Cloud One pieces for Split King; this bundle does not change the feel label. Contour5 restricts its Split King to a Saatva Split King adjustable base. Confirm exact pieces and base.

Open the finder with Split King and Medium selected. Compare RejuvenatePlus, Restore Cool Touch and excluded RestorePlus Cool Touch, PurplePlus, standard Restore, Contour5 and Memory Foam Hybrid; read the direct RestorePlus assessment for its separate feel label.

Use one PurplePlus plan for feel, size, height and base conditions

Decision: Queen, Medium, side guidance, conditional adjustable-base support and an exact 11-inch window select PurplePlus alone in this reviewed library; its 11-inch plan also carries a recorded 100 trial value. Restore Cool Touch is not counted because its height evidence is unresolved.

This combination works because the same PurplePlus plan lists the Queen size, Medium feel, side position, 11-inch height and adjustable-base compatibility. Restore Hybrid is another documented Medium side-position plan, but its 11.5-inch profile does not fit this exact 11-inch window. Restore Cool Touch has seller-listed Medium, side and base support but unresolved 11.5-/13-inch height statements; RestorePlus Cool Touch is listed at 13 inches and cannot meet this 11-inch window. The base condition is specific: Purple says it must be tested to at least 750 lb. The product page's 100-night headline and the policy's 100-calendar-day wording are not interchangeable return promises.

Open the finder with all seven PurplePlus scenario choices. Read the PurplePlus, Restore Hybrid, height-conflicted Restore Cool Touch and 13-inch RestorePlus Cool Touch assessments; verify the exact Queen code and base instructions.

PurpleRenew is excluded from strict height windows because the maker page conflicts between 11- and 11.5-inch claims; its plan height remains unknown pending clarification. Read the source assessment before relying on a clearance threshold.

Split King plus Firm

Decision: Split King plus a maker-described Firm option returns PurpleFlex, current Rejuvenate, the Classic and Zenhaven; Rejuvenate's exact 14.5-inch Split King is two Twin XL-size pieces, and Zenhaven's matching plan is its Gentle Firm face.

These are different setups: PurpleFlex is a fixed 8-inch Firm option; Rejuvenate's current Split King comprises two 80 × 38 × 14.5-inch pieces (code 10-21-24199, 104 lb each) but generic adjustable-base compatibility remains unresolved; Zenhaven is a 10-inch reversible mattress, and Saatva pairs its Split King size exclusively with Saatva Split King adjustable bases. Confirm exact split pieces and whether one feel for both pieces meets your need.

Open the finder with Split King and Firm selected. Compare PurpleFlex, Rejuvenate, Classic and Zenhaven; verify Rejuvenate's exact foundation guidance because its product page conflicts about adjustable bases.

Cloud One with a Medium Soft, stomach-position Queen setup at exactly 11 inches

Decision: The exact 11-inch scenario—Medium Soft, stomach-position maker guidance, Queen, adjustable-base requirement, and a 100-night trial headline—matches Casper Cloud One alone in this reviewed library. Casper labels Cloud One Medium Soft and gives its page specific stomach-sleeper emphasis; the broader FAQ supplies the separate side/back/stomach wording, and none of those claims predicts personal comfort.

The exact product selector lists Queen and an 11-inch plan; Casper's FAQ says its mattresses are designed for adjustable frames. The full fixed return fee remains unknown, so this scenario satisfies only the selected duration field, not a fee ceiling or a guarantee about return costs. Confirm the live order package and the conflicting slat-spacing instructions before setup. See the Cloud One assessment.

Open the finder with this exact 11-inch Cloud One scenario.

The same Cloud One scenario with an exact 11.5-inch minimum and maximum

Decision: No reviewed plan matches the same Medium Soft, stomach-position, Queen, adjustable-base and 100-night requirements in an exact 11.5-inch window; Cloud One's maker-listed 11-inch profile is one half-inch below the selected minimum.

This is a strict mattress-only height window, not a rounding allowance. Cloud One's published 11-inch profile cannot be treated as 11.5 inches. The exact current selector and profile are documented in the Cloud One assessment.

Open the finder with the same choices and an exact 11.5-inch window.

Minimum mattress height of 11 inches

The BR800 Medium and maker-listed 11.75-inch BRS900 Medium Firm both exceed this inclusive floor. Verify the retailer's exact selected profile before using a rounded item title for tight clearance.

Decision: An 11-inch minimum admits all four reviewed Casper plans and Beautyrest's 12-inch BR800 and maker-listed 11.75-inch Silver BRS900; The One and Cloud One are 11 inches, while Dream and Snow are 12.

Soothing Nights also qualifies through its 12-, 14- and 16-inch profiles, while its 10-inch Medium and 7-/8-inch plans fall below this floor. See the plan list; the finder link below applies this same 11-inch condition.

Dream and Snow also meet 11.5 inches, while The One and Cloud One do not. The 12-inch plans enter at an inclusive 12-inch floor. Compare the four separate The One, Cloud One, Dream and Snow reviews; all profiles are mattress-only.

This boundary concerns the mattress alone and does not establish a final bed height, clearance or suitability for a frame. If the minimum is a real setup need, check the selected foundation and the precise model package.

Open the finder with an 11-inch minimum. Read the Cloud One and The One assessments and check the mattress-only profile caveat.

Novaform boundary check: The exact 12-inch Back Support and 14-inch foam/hybrid/Serafina plans clear this floor; the 10-inch SoFresh does not. See the individual Advanced Back Support Plus; ComfortGrande Advanced foam; ComfortGrande Advanced Hybrid; Serafina PerfectTemp assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum mattress height of 10.5 inches

Decision: At a 10.5-inch maximum, all four Casper plans are excluded: The One and Cloud One are 11 inches, while Dream and Snow are 12 inches.

The half-inch boundary admits The One and Cloud One at an inclusive 11-inch cap; Dream and Snow enter only at 12 inches. Compare the separate The One, Cloud One, Dream and Snow assessments. This is mattress profile height only.

A half-inch is enough to change this exact fit filter. Do not round a mattress-only profile down or treat the foundation's height as part of the mattress measurement; compare the exact frame clearance separately.

Open the finder with a 10.5-inch maximum. See the Cloud One and The One profile assessments and compare the matching Purple Mattress, whose listed profile is 9.25 inches.

Novaform boundary check: The 10-inch SoFresh plan fits; taller new Novaform profiles do not yet enter. See the individual SoFresh Plus assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Maximum mattress height of 11 inches

Decision: An 11-inch maximum admits Casper The One and Cloud One at their listed profiles but excludes the 12-inch Dream and Snow; an 11.5-inch mattress such as Restore Hybrid also exceeds this ceiling.

The 12-inch Casper profiles enter at the inclusive 12-inch boundary, not at 11 or 11.5 inches. See Dream and Snow for their separate current specifications.

The two Casper models share an 11-inch profile but not a feel: Cloud One is Medium Soft, while The One is Medium-Firm. The result is a mattress-only threshold, not a foundation or total-bed clearance guarantee.

Open the finder with an 11-inch maximum. Compare the Cloud One and The One profiles with the excluded 11.5-inch Restore Hybrid; verify the exact base and bed height separately.

Novaform boundary check: The 10-inch SoFresh plan fits; taller new Novaform profiles do not yet enter. See the individual SoFresh Plus assessments. Each quoted profile is mattress-only; plan the base, frame and delivery path separately.

Earlier Casper models at the 10- and 11-inch maximum boundaries

Decision: With earlier models enabled, Queen and Medium selected, a 10-inch maximum returns four families including Casper Element, Saatva Murphy, Novaform SoFresh Plus and the exact 10-inch Medium Queen Soothing Nights plan; at 11 inches the result grows to six, retaining SoFresh and Soothing Nights and also admitting Original Hybrid and PurplePlus. The Casper Original foam remains Medium Firm, not Medium.

The archived Element is the exact 10-inch boundary case, while the archived Original Hybrid is an 11-inch Medium plan. The separate Original Mattress is also 11 inches, but its maker label is Medium Firm, so it does not enter this Medium comparison. This is mattress-profile height, not the height of a base, frame or finished bed. The maker's archive label does not certify future availability or personal comfort; compare each exact model's separate review and confirm the variant at checkout.

Open the exact Earlier + Medium + Queen + 10-inch maximum scenario. Read the Element, Murphy, Original Mattress and Original Hybrid evidence.

Open the same scenario with an 11-inch maximum. Compare Element, Original Hybrid, PurplePlus and Murphy, and compare the Medium Firm Original Mattress.

The new Novaform SoFresh Plus is a current 10-inch Medium Queen plan. It matches the inclusive 10- and 11-inch ceilings even though one promotional bullet says Medium Firm; the exact title/specification supply the matcher’s Medium label. Soothing Nights enters this exact Earlier=yes, Medium Queen combination through its 10-inch Medium Queen SKU 700813139-1050; the other profiles do not inherit that comfort label. Read the Soothing Nights assessment. The same-condition links above hold Earlier, Medium and Queen constant while changing only the ceiling; mattress height excludes the frame.

Earlier Casper models at the 10- and 11-inch minimum boundaries

Decision: With earlier models enabled, Queen and Medium selected, a 10-inch minimum returns 25 plans, including the original Dream Weaver's current-reference Medium Queen, Dream Weaver Hybrid's 11.5-inch Medium Queen, the 12-inch BR800 Medium, Novaform’s 10-inch SoFresh Plus, Soothing Nights' exact 10-inch Medium Queen and three separate 14-inch Medium Novaform families. At 11 inches the result is 21: both Dream Weaver families, BR800 and the 14-inch plans remain while SoFresh and Soothing Nights' 10-inch Medium plan fall below the floor.

The Original Hybrid remains at 11 inches and qualifies at this inclusive minimum; Original Mattress shares that profile but carries a different Medium Firm maker label. Novaform Platinum is a separate 16.5-inch Queen/Medium plan and clears both this and the 11-inch floor. The 10- and 11-inch figures are separate manufacturer-listed mattress profiles, not independent measurements or total bed heights. An inclusive minimum is not a maximum, so use a ceiling as well if you have a strict clearance limit.

The current Costco foam Cooling Select is a separate 12-inch Medium-labeled plan and therefore remains in both Queen/Medium minimum-height results. Its hybrid names the same size and height but stays out of this Medium interaction because the exact Costco title says Medium Firm while the table says Medium. Compare Cooling Select foam with the separate hybrid assessment.

The separate current-reference BR800 Medium also lists Queen and a 12-inch profile, so it clears both 10- and 11-inch minimums under this Medium filter. Do not substitute the Silver BRS900, whose exact manufacturer plan is Medium Firm, for this Medium-labelled model.

Novaform's separate Medium Legacy Premier Support plan lists Queen at 14 inches, so it clears both minimums; its Firm page is a distinct option and does not match the selected Medium feel. The 16.5-inch Platinum Medium Queen plan also clears both floors; compare the Legacy review and the Platinum assessment. Neither model page names an adjustable-base approval.

Open the exact Earlier + Medium + Queen + 10-inch minimum scenario. Compare the current-reference Dream Weaver Hybrid at 11.5 inches with Element at 10 inches, the 11-inch Original Hybrid and Novaform's 14-inch plan with Murphy.

Open the same scenario with an 11-inch minimum. Dream Weaver Hybrid remains at its exact 11.5-inch Medium Queen profile; compare the Hybrid review with the Original Hybrid profile and 14-inch Novaform Medium plan and the distinct Original Mattress, which remains Medium Firm rather than Medium.

The new SoFresh Plus at 10 inches is present in the 10-inch minimum case and falls below the inclusive 11-inch floor. The separate ComfortGrande all-foam, ComfortGrande hybrid and Serafina Medium are each 14 inches and remain in both cases. Soothing Nights' exact 10-inch Medium Queen plan follows the same threshold: it qualifies for min-height 10, but not 11; its 8-inch Medium and separate 10-inch Medium-Plush Pillow Top are not the selected Medium plan. Read the review. The paired links above keep Earlier, feel and Queen fixed; only the minimum changes.

Twin

The Dream Weaver family lists a Twin size for each of its six profile groups; its maker SKU suffix is 1010. The separate Hybrid also lists Twin in both its 11.5-inch Medium SKU 700812186-1010 and 12.5-inch Plush SKU 700812187-1010. Soothing Nights lists Twin across all nine profiles with suffix 1010; the rows are sizes of one family, not nine independent models. Neither family's Twin row is a split-size set. Read the six-plan review, the Hybrid review, the Soothing Nights assessment and open the finder with only Twin selected.

Twin XL

The non-XCS Black Hybrid Series Four lists standard Twin XL in Firm Apex Top SKU 700812447-1020 and Plush Apex Top SKU 700812489-1020; neither is a split pair. See the non-XCS Series Four review or open the finder with only Twin XL selected.

The Dream Weaver family lists Twin XL for each of its six profile groups; its maker SKU suffix is 1020. The Hybrid's distinct Medium and Plush Twin XL SKUs are 700812186-1020 and 700812187-1020. Soothing Nights lists Twin XL in each of its nine profile groups with suffix 1020; confirm the profile prefix as well as the size suffix. Black Hybrid Series Three XCS also lists Twin XL in Firm, Medium and Plush; for example, the Firm SKU is 700813275-1020. These are standard one-piece Twin XL choices, not evidence for two units or a split set. Read the six-plan review, the Hybrid review, the Soothing Nights assessment, the Series Three XCS assessment and open the finder with only Twin XL selected.

Series Four XCS lists a standard Twin XL in both Firm (SKU 700813278-1020) and Medium (700813279-1020); no two-piece split configuration is implied. Read the Series Four XCS research-based review and open the finder with the same size twin-xl condition.

Full

For non-XCS Black Hybrid Series Four Full, the Firm Apex Top SKU is 700812447-1030 and the Plush Apex Top SKU is 700812489-1030. Verify the selected feel as well as Full in the final order. See the non-XCS Series Four review or open the finder with only Full selected.

The Dream Weaver ProductGroup lists a Full-size maker SKU in each of its six profile groups; the suffix is 1030. The Hybrid's separate Medium and Plush Full SKUs are 700812186-1030 and 700812187-1030. Soothing Nights also lists Full across its nine profiles with suffix 1030; verify the model prefix and size when ordering. Confirm that the seller's selected feel and exact Full code agree. Read the six-plan review, the Hybrid review, the Soothing Nights assessment and open the finder with only Full selected.

Queen

The non-XCS Black Hybrid Series Four standard Queen SKUs are 700812447-1050 for Firm Apex Top and 700812489-1050 for Plush Apex Top; its ProductGroup leaves GTIN blank. These are not Series Four XCS codes. See the non-XCS Series Four review or open the finder with only Queen selected.

The Dream Weaver ProductGroup lists Queen in all six profiles with size suffix 1050, but the six model codes refer to different heights and feels. The separate Hybrid Queen SKUs are 700812186-1050 for the 11.5-inch Medium and 700812187-1050 for the 12.5-inch Plush. Soothing Nights lists Queen across its nine profiles using suffix 1050; its 10-inch Medium Queen SKU is 700813139-1050. Black Hybrid Series Three XCS includes Queen in all three feels: the Firm SKU is 700813275-1050, with separate Medium and Plush prefixes 700813276 and 700813277. Its Split Head Queen SKU ends 1059 and is a separate adjustable-head configuration, not a normal Queen code. Measure mattress height separately from the frame and foundation. Read the six-plan review, the Hybrid review, the Soothing Nights assessment, the Series Three XCS review and open the finder with only Queen selected.

Series Four XCS lists both standard Queen and Split Head Queen; the standard SKU suffix is 1050, while 1059 is a separate split-head variant. Read the Series Four XCS research-based review and open the finder with the same size queen condition.

King

The non-XCS Black Hybrid Series Four lists standard King under both feels: Firm Apex Top SKU 700812447-1060 and Plush Apex Top SKU 700812489-1060. It does not list Split King. See the non-XCS Series Four review or open the finder with only King selected.

The Dream Weaver ProductGroup lists standard King for all six profile groups using suffix 1060; it does not list Split King. The Hybrid also offers standard King as 700812186-1060 Medium and 700812187-1060 Plush, not a split pair. Soothing Nights lists King in each of its nine profile groups using suffix 1060, with no Split King option on the exact page. Black Hybrid Series Three XCS offers standard King under all three feel prefixes; the Firm SKU is 700813275-1060. Its other King configuration is Split Head King ending 1069, not Split King; the exact page has no split pair. Check the exact feel/SKU and the frame's center-support requirements. Read the six-plan review, the Hybrid review, the Soothing Nights assessment, the Series Three XCS review and open the finder with only King selected.

Series Four XCS lists standard King (suffix 1060) and a separate Split Head King (suffix 1069); neither is a Split King mattress pair. Read the Series Four XCS research-based review and open the finder with the same size king condition.

California King

The non-XCS Black Hybrid Series Four lists Cal King under Firm Apex Top SKU 700812447-1070 and Plush Apex Top SKU 700812489-1070; neither is a split California King. See the non-XCS Series Four review or open the finder with only California King selected.

The Dream Weaver ProductGroup lists Cal King in all six profile groups using suffix 1070; no split California King configuration appears. The Hybrid Cal King options are 700812186-1070 Medium and 700812187-1070 Plush; its exact family page likewise has no split Cal King row. Soothing Nights lists Cal King across its profiles with suffix 1070 and no Split Cal King choice; a 10-inch Medium Cal King has SKU 700813139-1070. Black Hybrid Series Three XCS lists California King in Firm, Medium and Plush; its Firm SKU is 700813275-1070 and no split Cal King option is listed. The original 11.5-inch Firm entries have no maker GTIN in their captured group, so use the exact SKU and selected plan rather than assuming a UPC. Read the six-plan review, the Hybrid review, the Soothing Nights assessment, the Series Three XCS review and open the finder with only California King selected.

Series Four XCS lists Cal King under Firm and Medium with suffix 1070; the product page does not list Split California King. Read the Series Four XCS research-based review and open the finder with the same size california-king condition.

Maximum height

The non-XCS Black Hybrid Series Four does not state an overall height for any of its ten feel/size variants. Because the selector-specific height is unknown, a 15-inch ceiling—and other numeric ceilings—cannot confirm this family’s fit. Ask for the exact dimensions; see its research-based review or open the finder with a 15-inch maximum.

The original Dream Weaver's profile facts are 11.5, 12.25, 12.5, 13.75 and 14.25 inches; on the valid half-inch maximum slider they first enter at ceilings of 11.5, 12.5, 12.5, 14 and 14.5 inches respectively. The separate Dream Weaver Hybrid is 11.5 inches in Medium and 12.5 inches in Plush: Medium first enters at 11.5, and Plush at 12.5. At 12, only the Hybrid Medium profile fits; at 12.5 and higher both do. Soothing Nights lists six mattress profiles—7, 8, 10, 12, 14 and 16 inches: its 7-inch plan is within a 7-inch cap, and the 8-inch plan enters at an 8-inch cap; each family match is based on at least one qualifying plan. Purple's distinct New PurpleFlex is separately listed at 8 inches. Black Hybrid Series Three XCS has a comparison graphic saying “up to 14.5 in,” but no exact selector-linked height for its feel/size variants, so it is excluded from hard maximum-height matching rather than assumed to fit at a 14.5-inch ceiling. Read its review before relying on clearance. Review the exact Soothing Nights plans and compare the same-condition 7-inch, 8-inch, 10-inch, 12-inch and 16-inch ceiling searches. These are mattress-only values, not frame or finished-bed heights. Read the original six-plan review and the Hybrid review.

Series Four XCS publishes no exact height for either selected feel. A comparison illustration saying “up to 15 inches” is not a variant value; the unknown does not pass a maximum-height filter. Read the Series Four XCS research-based review; check the finder with the illustrated numeric boundary.

Minimum height

The non-XCS Black Hybrid Series Four does not state an overall height for any of its ten feel/size variants. Unknown height cannot meet a numeric minimum, including 15 inches; obtain the exact selected dimensions rather than infer from nearby models or artwork. See its research-based review or open the finder with a 15-inch minimum.

A 14-inch minimum still includes the original Dream Weaver through its two 14.25-inch Pillow Top profiles, but a 14.5-inch minimum excludes every original plan. For the separate Hybrid, both plans clear 11.5 inches, only its 12.5-inch Plush clears 12 or 12.5, and neither meets 13. Soothing Nights' 7-, 8-, 10-, 12-, 14- and 16-inch profiles mean a 10-inch minimum admits the 10/12/14/16-inch plans but not 7 or 8; a 14.5-inch minimum leaves only its 16-inch plan, while a 16.5-inch minimum excludes the family. Black Hybrid Series Three XCS is not numerically matched for minimum height: “up to 14.5 in” in a comparison graphic is not an exact height tied to its selected feel/size, so no valid minimum boundary can be inferred from it. Confirm exact clearance in its review. Confirm the selected SKU in the Soothing Nights model review and use the exact 10-inch, 14.5-inch, 16-inch and 16.5-inch minimum searches. These figures describe the mattress only. Read the six-plan review and the Hybrid review.

Series Four XCS publishes no exact height for either selected feel. A comparison illustration saying “up to 15 inches” is not a variant value; the unknown does not pass a minimum-height filter. Read the Series Four XCS research-based review; check the finder with the illustrated numeric boundary.

Maximum height: 11 inches

An 11-inch maximum excludes all Dream Weaver profiles because the shortest exact plan is 11.5 inches. It also excludes Dream Weaver Hybrid: its shortest exact profile is 11.5-inch Medium, with a separate 12.5-inch Plush plan. The figures are mattress-only. Compare the separate low-profile Casper Cloud One, Casper The One and Novaform SoFresh Plus reviews, then read the original Dream Weaver and Hybrid reviews for their different profile sets. Open the finder with an 11-inch maximum.

Maximum height: 11.5 inches

At an inclusive 11.5-inch maximum, the original Dream Weaver 11.5-inch Firm and the separate Dream Weaver Hybrid 11.5-inch Medium enter; the Hybrid's 12.5-inch Plush plan does not. These are distinct product families and exact comfort selectors. Read the six-plan original review, the two-profile Hybrid review and open the finder with an 11.5-inch maximum.

Minimum height: 14 inches

A 14-inch minimum retains Dream Weaver through its two 14.25-inch Pillow Top plans, while its other four profiles fall below this floor. Read the six-plan review and open the finder with a 14-inch minimum.

Minimum height: 14.5 inches

A 14.5-inch minimum excludes Dream Weaver because its tallest listed profile is 14.25 inches; this remains a mattress-only measurement. For reviewed taller alternatives, compare Saatva Classic, Saatva HD, Purple RejuvenatePlus and Purple RejuvenateUltimate; read the Dream Weaver review for the exact heights excluded. Open the finder with a 14.5-inch minimum.

Assessment scenario: Earlier, Medium-Firm, Queen, maximum 11 inches

The earlier Casper Essential 2025 joins the Queen, Medium-Firm result at its inclusive 11-inch maximum; this is mattress height, not a full bed measurement. Its exact archived product page gives an 11-inch profile. Current orderability is not established by the live redirect.

Read the Essential 2025 evidence-based review, compare the separate Casper The One review, or open the finder with the same four choices.

Assessment scenario: Earlier, Medium-Firm, Queen, maximum 10 inches

At 10 inches, the same earlier Essential 2025 Queen plan fails the cap because its archived exact profile is 11 inches. A lower-profile model that meets the remaining choices may still match; the Essential does not pass this inclusive ceiling.

Check the exact profile and generation distinction, compare the Purple Mattress review, or open the finder with the same four choices and 10-inch cap.

Assessment scenario: Earlier, Medium-Firm, Queen, minimum 11 inches

An 11-inch minimum admits the earlier Casper Essential 2025 Queen plan at its stated profile; the exact page labels it Medium-Firm. This is the inclusive mattress-only floor, not a measurement of the base or assembled bed.

Read the model-specific review, compare the distinct Casper The One review, or open the finder with the same four choices.

Assessment scenario: Earlier, Medium-Firm, Queen, minimum 12 inches

A 12-inch minimum excludes the Essential 2025 11-inch plan, while taller exact plans may still match. The page's archived profile establishes the Essential's mattress height only; it does not settle any complete bed clearance.
