About Novaform

Novaform is Costco's exclusive mattress brand, made by Innocor, and it is one of the highest-volume foam mattress lines in the country simply because of the retail footprint behind it.

The best-known models are the ComfortGrande and the DreamAway and Serafina Pearl gel memory foam beds, plus a long-running topper range that many shoppers know better than the mattresses.

The value case is straightforward: Costco's return policy is the most generous in retail, and Novaform pricing tends to sit below equivalent-thickness DTC foam beds. The trade-off is limited firmness choice and comfort foams that soften sooner than premium equivalents.

What they make

Gel memory foam mattresses and toppers sold exclusively through Costco warehouses and Costco.com.

Origin

Manufactured for Costco by Innocor

Novaform Signature Technologies

Gel Memory Foam Comfort Layers

Gel-infused memory foam intended to slow heat build-up in an otherwise dense foam stack.

Thick Comfort Profiles

14-inch builds with deep comfort layers, unusual in this price band and the reason the ComfortGrande is so popular.

Costco Return Policy

Not a material, but the practical benefit: Costco's member return policy is more forgiving than any mattress sleep trial.

Best for

Costco members who want the safest possible return path
Side sleepers who want deep foam contour on a budget
Guest rooms and secondary bedrooms
Topper buyers wanting a cheap comfort upgrade

Not ideal for

Hot sleepers — these are dense all-foam beds
Heavier sleepers needing coil support
Shoppers who want a firmness ladder to choose from

How Much Does a Novaform Mattress Cost?

Novaform queens run $500–$1,100 across the lineup (budget to mid tier). The table below estimates the rest of the size ladder from that queen range using the standard size pricing brands apply — the low column tracks the entry model, the high column the flagship. Treat these as planning estimates rather than quotes: promotions move real street prices by 20–30% for weeks at a time.

Novaform FAQ

Who makes Novaform mattresses?

Innocor manufactures Novaform exclusively for Costco. The brand is not sold through other retailers, which is why comparison shopping on it is difficult.

Is the Novaform ComfortGrande any good?

It is a deep, plush 14-inch gel memory foam bed that suits side sleepers who want contour on a budget. It runs warm and softens faster than premium foam, but at Costco pricing with Costco returns behind it, the risk is low.

Can you return a Novaform mattress to Costco?

Costco's member return policy applies, and it is considerably more generous than a standard mattress sleep trial. Check current policy terms with the warehouse before buying, since the details can change.
