Beautyrest Black Hybrid Series One: exact plan and fit boundaries
This guide maps the exact Beautyrest Black Hybrid Series One selectors to the mattress finder's public choices. It is a source-based fit reference, not a personal comfort prediction, retail availability check or substitute for verifying the variant shown at checkout. The separate Series One review examines the design, source limits, purchase checks and maker terms in more detail.
Start with the exact selector and plan
The manufacturer page lists Firm, Medium and Plush across Twin XL, Full, Queen, King and California King. It does not list Twin, Split King or Split California King. Firm, Medium and Plush are maker labels, not a common numerical firmness scale. The Queen heights below are narrower retailer observations tied to exact Queen SKUs; they do not establish the height of other sizes.
Side-position choice
Series One's Medium and Plush choices are the plans associated with side-sleeper cushioning in Beautyrest's series guidance; Firm is not tagged for side sleeping. This is general manufacturer guidance, not an individual comfort promise. Read the Series One review or open the finder with only side selected.
Back-position choice
Series One's Firm and Medium choices fall within Beautyrest's stated back-sleeper guidance; Plush is not assigned that back-position tag. The maker's guidance is a starting point, not a guarantee of how a person will feel. Read the Series One review or open the finder with only back selected.
Stomach-position choice
Series One's exact Firm overview names back and stomach sleepers; Medium and Plush do not inherit that specific stomach guidance. This is maker wording, not individualized fit advice. Read the Series One review or open the finder with only stomach selected.
Plush Soft is not the maker's Plush
Series One's exact selector says “Plush,” not “Plush Soft,” so it is not normalized into the finder's Plush Soft choice. The separate Plush selector remains visible in the Series One review; for exact Plush Soft-labelled matches, compare the Saatva Classic and Saatva Youth. Open the finder with only Plush Soft selected.
Firm choice
Series One offers Firm across all five listed sizes, with exact maker SKU prefixes retained in the review and no calibrated numeric firmness score. Read the Series One review or open the finder with only Firm selected.
Medium choice
Series One offers Medium across all five listed sizes; “Medium” remains its exact maker label and does not imply a cross-brand number. Read the Series One review or open the finder with only Medium selected.
Choose the listed size, not a look-alike split set
Twin XL
Series One lists standard Twin XL for Firm, Plush and Medium: the maker SKU suffix is 1020, with respective prefixes 700812439, 700812438 and 700812440. These are one-piece Twin XL mattresses, not a split pair. Read the Series One review or open the finder with only Twin XL selected.
Full
Series One lists Full under all three exact feels: Firm 700812439-1030, Plush 700812438-1030 and Medium 700812440-1030. Verify the selected label and exact maker code at checkout. Read the Series One review or open the finder with only Full selected.
Queen
Queen SKUs are 700812439-1050 Firm, 700812438-1050 Plush and 700812440-1050 Medium; these are different selector plans, and the ProductGroup leaves GTIN blank. Read the Series One review or open the finder with only Queen selected.
King
Series One lists standard King under all three feels: Firm 700812439-1060, Plush 700812438-1060 and Medium 700812440-1060. It does not list Split King. Read the Series One review or open the finder with only King selected.
California King
Series One lists California King under Firm 700812439-1070, Plush 700812438-1070 and Medium 700812440-1070; it does not list a split California King. Read the Series One review or open the finder with only California King selected.
Adjustable-base requirement
Series One meets the finder's adjustable-base requirement only within Beautyrest's statement that current mattresses have been tested with Beautyrest-branded adjustable bases. That does not approve every third-party frame or show that a base is included. Read the Series One review and open the finder with compatible adjustable-base support required.
Weight guidance and seller terms are separate questions
Lighter-body guidance
Beautyrest does not publish a Series One model-specific lighter-body recommendation or weight capacity, so this model is not tagged for the lighter-body guidance choice. The distinct Saatva Classic Plush Soft has that documented maker guidance. Open the finder with lighter-body guidance selected.
250–300 lb maker guidance
Series One has no model-specific 250–300 lb recommendation or capacity statement, so this guidance option does not tag it. The distinct Saatva Classic Firm carries the matching maker guidance; it is not a universal load rating. Open the finder with the 250–300 lb guidance option.
Under-130 lb maker guidance
Series One publishes no exact under-130 lb guidance or weight capacity, so it does not meet this tag. The separate Saatva Rx has the specific under-130 lb stomach-sleeper wording; it is not a capacity claim for Series One. Open the finder with under-130 lb guidance selected.
300–500 lb maker guidance
No model-specific 300–500 lb recommendation or capacity is stated for Series One, so it does not receive this guidance tag. The distinct Saatva HD Medium Firm carries its own maker guidance, not a universal weight limit. Open the finder with the 300–500 lb guidance option.
Exclude earlier models
Series One is recorded as a current-reference U.S. family, so it remains eligible when earlier products are excluded. This catalogue status does not verify a seller's current stock. Read the Series One review or open the finder with earlier models excluded.
Include earlier models
Including earlier models does not remove current-reference Series One; the toggle broadens the set without proving a seller's current availability. Read the Series One review or open the finder with earlier models included.
Use only sourced numerical boundaries
Maximum mattress height
Only three Queen heights are established here: Firm and Plush are each 12.5 inches; Medium is 13 inches. Thus a 12-inch maximum excludes the documented Queen plans, a 12.5-inch maximum admits the Firm/Plush Queen plans, and a 13-inch maximum also admits Medium Queen. Heights for Twin XL, Full, King and California King remain unknown and fail closed; these figures are mattress-only, not a bed-frame stack. Read the review's source limits, then open the finder with a 12.5-inch ceiling or with a 13-inch ceiling.
Minimum mattress height
For documented Queen plans, the inclusive floor boundaries are 12.5 inches for Firm/Plush and 13 inches for Medium. A 12.5-inch minimum admits the first two; a 13-inch minimum admits only Medium Queen. The other four sizes have no established height and do not pass a numeric minimum. These are mattress-only values. Read the review's height evidence or open the finder with a 12.5-inch floor.
Minimum trial length
The Series One page displays a 100-night in-home trial: that meets a 100-night minimum, not 101 nights. The separate free-label or pickup terms belong only to eligible direct Beautyrest.com or BeautySleep.com orders. Read the Series One review or open the finder with a 100-night minimum.
Zero-dollar return-fee ceiling
A $0 pickup-fee result applies only to eligible manufacturer-direct Beautyrest.com/BeautySleep.com orders under the published return policy; it is not a retailer-wide return-cost fact. Check the actual seller, eligibility and one-return-per-household limit. Read the Series One review or open the finder with a zero-dollar fee ceiling.
How feel, position, size, height and terms combine
Firm, back guidance, Queen, a required compatible base, a 12-to-12.5-inch window, 100 nights and a $0 direct-return-fee ceiling return Series One Firm Queen and the distinct Dream Weaver Firm Queen. The 12.5-inch edge is inclusive; maker SKU 700812439-1050 is the Firm Queen code. Compare the Series One review with the Dream Weaver review. Open the same eight-condition finder scenario.
Keep those conditions but tighten the maximum to 12 inches: no reviewed plan remains. Series One Firm Queen is 12.5 inches and fails that ceiling; do not infer a shorter profile from another size. Open the same requirements with a 12-inch height window.
Restore the inclusive 12.5-inch ceiling but increase only the trial minimum to 101 nights: no result remains because Series One's page says 100 nights. The direct pickup policy does not extend the advertised trial length. Open the same scenario at 101 nights.
Medium, side guidance, Queen, a required compatible base and an exact 13-inch height window meet the Series One Medium Queen plan; the maker's Queen SKU is 700812440-1050. Its 100-night/$0 terms remain conditional on eligible direct orders. Open the same eight-condition Medium scenario.
Raise only that Medium scenario's trial minimum to 101 nights and it no longer matches Series One. Always verify an outside seller's separate return terms. Open the same Medium request at 101 nights.
Check the seller and the exact item
The manufacturer's trial and warranty headlines do not guarantee a third-party seller's policies. Before ordering, match the family name, exact feel, size and SKU to the offer; confirm mattress dimensions, base instructions, trial/return rules and written warranty with that seller. The Series One image in the review represents the official Firm product image only, not an exact Plush or Medium assembly. See Beautyrest's Series One family page, its Black Hybrid series comparison, adjustable-base FAQ, direct return policy and written warranty page. No price, stock, customer rating or independent product-test result is inferred here.
