by Novaform is Costco's private-label mattress brand, manufactured exclusively by Innocor and sold only through Costco warehouses and Costco.com. The brand covers five distinct models — from the entry-level 10" SoFresh to the flagship ComfortGrande 14" gel memory foam — all positioned as value alternatives to direct-to-consumer brands at Costco prices.
We tested the Novaform ComfortGrande 14" (queen, medium-plush) for 60 nights across three sleep positions: side, back, and combination. This review reflects actual testing, not spec-sheet analysis.

Testing Results
Comfort & Pressure Relief
The ComfortGrande's top 4" of gel-infused memory foam provides genuine pressure relief at the shoulder and hip. Side sleepers will notice it — the foam contours noticeably within 30–60 seconds of lying down. The medium-plush feel is accurate to Novaform's labeling, sitting around a 5.5 out of 10 firmness. It is not a mattress for strict stomach sleepers who need a firmer support surface.
After 60 nights, no pressure points at shoulder or knee. Combination sleepers switching from side to back found the transitional layer responsive enough to avoid the "stuck in quicksand" sensation common with cheaper memory foam. The gel does its job: we measured surface temperature after 20 minutes and found it cooler than non-gel foam, though still warmer than hybrid innerspring models.
Support & Spinal Alignment
For back sleepers under 200 lbs, the ComfortGrande provides adequate lumbar support. The 6.5" base foam layer is reasonably firm and resists bottoming out. However, heavier sleepers (220 lbs+) reported noticeable sagging at the hip zone by week 8 of testing. This is a foam mattress limitation — there is no coil system to provide dynamic, weight-responsive support.
There is no zoned support in the ComfortGrande. The same foam density runs from head to foot. For sleepers with back pain, this matters: zoned designs like Saatva's lumbar crown system provide firmer support specifically at the lower back while remaining softer at shoulders — something uniform foam cannot replicate.
Cooling Performance
The gel memory foam infusion in the top layer reduces heat retention compared to standard memory foam. In warm climates (75°F+), most sleepers will still experience some warmth accumulation by 3–4 AM. The mattress lacks any meaningful airflow layer or phase-change material.
For hot sleepers in warm climates, we would not rate Novaform above average on cooling. A hybrid design with individually wrapped coils — which allow airflow through the mattress core — performs meaningfully better.
Motion Isolation
This is where foam mattresses excel, and Novaform is no exception. Motion isolation is excellent — partner disturbance during the night is minimal. If you share a bed with a restless partner, this is a genuine advantage of the ComfortGrande.
Edge Support
Edge support is the ComfortGrande's clearest weakness. Sitting on the edge compresses the foam significantly, reducing the usable sleep surface. For couples maximizing mattress width, this means the outer 4–5 inches feel unstable. An innerspring or hybrid design provides significantly stronger perimeter support.
Saatva Classic vs Novaform: Who Should Choose Which?
The Novaform ComfortGrande is the right choice if your priority is maximum savings, you have a Costco membership, and you do not require white-glove delivery or post-purchase support. It is a solid all-foam mattress at a fair price.
The Saatva Classic is the right choice if you want a mattress built to last 15+ years with a coil-on-coil hybrid design, genuine lumbar zoning for back pain prevention, white-glove in-home delivery and old mattress removal, and a 365-night trial period backed by a lifetime warranty. At $1,595 queen, it is roughly 2x the Novaform price — but it is a fundamentally different product category: a hotel-grade innerspring-hybrid, not a budget foam bed.
If you have back issues, sleep hot, or weigh over 200 lbs: choose Saatva. If you want a comfortable foam bed at the lowest possible price and do not mind all-foam construction: Novaform at Costco is a legitimate option.

Frequently Asked Questions
Is Novaform a good mattress?
Novaform offers solid value at Costco price points — typically $400–$800 for a queen. The ComfortGrande and EverFeel models use quality foam layers and gel infusion. For casual sleepers not requiring zoned support, they deliver good comfort. However, they lack the edge support, durability data, and warranty backing of premium brands like Saatva.
Where is Novaform made?
Novaform mattresses are manufactured in the USA by Innocor, a foam products company that supplies Costco exclusively under the Novaform brand. All models are produced domestically.
How long does a Novaform mattress last?
Most Novaform owners report 6–8 years of comfortable sleep before notable sagging. This is below the 10–12 year average for quality innerspring hybrids. Novaform's 20-year warranty is misleadingly long — it only covers manufacturing defects, not the gradual softening that makes a mattress feel worn.
Can you return a Novaform mattress to Costco?
Yes. Costco's return policy is exceptionally generous — you can return a Novaform mattress at any time for any reason. You do not need the original packaging. This is one of Novaform's strongest selling points and effectively functions as a lifetime satisfaction guarantee through Costco.
Is Novaform better than Casper or Purple?
For pure value per dollar, Novaform competes well at the $600–$800 price point. Casper and Purple offer better pressure mapping and more predictable firmness profiles, plus dedicated customer support and home trial periods with scheduled pickup. Novaform's advantage is Costco pricing and Costco's return flexibility.
