A useful fit for

A source-based option for a shopper seeking a Medium-labeled 14-inch all-foam Queen, King or one of the other maker-listed sizes, and who wants the page’s explicit adjustable-base statement.

The main tradeoff

Its Medium label has no numerical scale, and the page gives no position/body guidance, exact home-trial length or fixed return fee. The similarly named hybrid is a distinct coil-containing construction, not a size/feel variation.

How does the foam ComfortGrande differ from the hybrid?

The ComfortGrande Advanced 14-inch foam mattress is the all-foam version: Novaform describes a 3-inch gel-memory-foam layer, 3-inch air-channel foam and 8-inch base. Its separately listed ComfortGrande 14-inch Advanced Hybrid adds coils and a firm border. The manufacturer names the foam version Medium; these claims do not prove which will feel cooler or more supportive.

Which exact sizes are selectable?

The manufacturer’s public variant list contains Twin, Full, Queen, King and California King. The specification table gives the Twin as 38 × 75 × 14 inches and the California King as 72 × 84 × 14; match the selected size on the exact seller page and law tag before ordering.

Can it be used with an adjustable base?

Novaform states adjustable-base compatibility on this exact product page. The general setup text also specifies airflow/support conditions for standard foundations, and it does not name a brand/model or articulate range. Confirm size-specific instructions, packaging, exact offer and written warranty terms with the seller.

The Novaform ComfortGrande Advanced 14-inch Gel Memory Foam Mattress is a separate all-foam family from the similarly named ComfortGrande 14-inch Advanced Hybrid. This assessment uses the exact product page and size endpoint; it is not a claim of ownership, hands-on use or performance testing. Both pages use the Medium label, but only the hybrid source lists coils.

What the foam version actually lists

Novaform describes a three-layer, 14-inch build: three inches of EVENcor GelMAX memory foam, three inches of air-channel foam and eight inches of base foam. Its page links phase-change gel to temperature regulation and describes a cool-touch quilted cover. It also describes support, pressure relief and motion isolation. These are maker descriptions and design intentions, not measured cooling, alignment, motion-transfer or durability outcomes.

The exact page’s title and specification table say Medium. One promotional bullet calls it Medium Firm, so I preserve that inconsistency rather than recategorizing the plan as Medium Firm. No numerical score or cross-brand scale explains the difference. The maker does not give an exact-position list or body-weight recommendation for this mattress, so the foam construction and general alignment language do not establish that it fits a particular sleeping position.

Five size variants, with one unusual Twin dimension

The selector and public variant endpoint list Twin, Full, Queen, King and California King. The maker lists Twin as 38 by 75 by 14 inches and 49.9 pounds; Full as 54 by 75 by 14 inches and 70.7 pounds; Queen as 60 by 80 by 14 inches and 83.9 pounds; King as 76 by 80 by 14 inches and 106.2 pounds; and California King as 72 by 84 by 14 inches and 105.6 pounds. These are source specifications, not measurements made for this review. I retain the published 38-inch Twin width rather than substituting a conventional reference dimension.

Every size is still a 14-inch mattress, not a finished bed-height measurement. Add the frame and support surface before checking fitted sheets, headboard clearance or accessibility. The public endpoint’s numeric product and variant IDs are internal manufacturer identifiers; its retail SKU and barcode fields are blank. They should not be treated as a Costco item number or ASIN.

Keep it separate from the hybrid

The companion ComfortGrande Advanced Hybrid has a wrapped-coil unit, a firm foam border and only Queen/King choices in its current exact endpoint. This foam model instead uses an eight-inch foam base and lists five size variants. That is a meaningful construction and fit distinction even though the two are the same overall height and share a Medium label. A shopper comparing these two should first decide whether a coil layer is a requirement, then verify the selected size and exact product title in the seller’s listing.

Support rules and adjustable-base statement

The exact product page says the mattress is compatible with adjustable bases. It does not name an approved base, lifting range or size-by-size articulation limit. Novaform’s general FAQ on the same page recommends a standard box spring or ventilated support with slats spaced less than six inches apart and warns against floor or flat-solid placement. Do not treat the generic support note as an exhaustive base compatibility specification; confirm the exact frame instructions and warranty conditions.

For care, Novaform says to spot-clean the foam, describes the foam as CertiPUR-US certified and says the mattress is fiberglass-free. Those are maker statements. Use the sewn care label and avoid relying on the page’s cooling language as evidence that the surface will feel a particular way to you.

Recall, warranty and orderability are not interchangeable

Novaform gives a 20-year limited-warranty headline, but the full booklet and seller-specific terms are not provided on this exact page. No model-specific home-trial duration or fixed return-pickup fee is established. The 2023 manufacturer/CPSC notice names certain ComfortGrande 14-inch item numbers and factory/date lots. The exact current page calls this a ComfortGrande Advanced foam model, while its variant endpoint contains no retail SKUs or law-tag details that bridge it to the recall list. That leaves the status of a specific offer unconfirmed; check the exact retailer item and law tag rather than assuming that a shared name proves either inclusion or clearance.

The page’s retailer selector and generic out-of-stock notice do not prove a deliverable offer. The endpoint’s availability flags are not a guarantee of stock in a particular store, seller or ZIP code.

Who should keep comparing

This is a plausible paper candidate if you want a 14-inch all-foam mattress with a named Medium option, a size range that includes California King and an explicit adjustable-base statement. It is less well documented for shoppers who need a sleep-position recommendation, exact weight guidance, a numeric firmness scale, or a confirmed return policy. Verify the exact “Advanced” model suffix, size, Twin dimensions, law tag, base and written warranty before placing an order.

Bottom line

The primary evidence supports a five-size, 14-inch, Medium-labelled foam mattress, distinct from Novaform’s coil-containing hybrid. It does not resolve the page’s Medium/Medium Firm wording, a personal comfort result, trial/return terms, current stock or the item-level recall bridge. Use those limits as purchase checks, not as an invitation to fill gaps with facts from the neighboring model.
