Zinus Green Tea 12″ Memory Foam — Most-reviewed budget mattress on Amazon
Price: ~$200 queen | Amazon return policy | 10-year warranty
Costco is known for value, and their mattress selection delivers on that reputation. Costco carries a curated selection of premium brand mattresses at prices significantly below retail — if you’re a Costco member, it’s worth checking their mattress section before buying elsewhere.
What Costco Sells
Costco’s mattress selection rotates, but typically includes Novaform (their exclusive foam brand), Sealy, Stearns & Foster, and occasionally Tempur-Pedic. Novaform is Costco’s premium private-label foam line and consistently receives strong reviews from members.
Novaform is a Costco exclusive brand that provides memory foam quality comparable to brands selling at 2x the price elsewhere. The 14-inch ComfortGrande is one of Costco’s top-selling mattresses and regularly reviewed as excellent value.
Costco carries select Sealy models at prices meaningfully below traditional mattress stores. Sealy’s Posturepedic line offers brand-name quality with Costco’s strong return policy backing the purchase.
Costco’s Return Policy
Costco’s return policy on mattresses is famously generous — they’ll accept returns with no time limit if you’re not satisfied (with some exceptions). This effectively gives you an unlimited trial period, removing one of the biggest risks in mattress buying. This policy alone is worth significant consideration.
For those who can stretch to premium, Costco occasionally carries Stearns & Foster luxury mattresses at prices $500-$800 below what mattress stores charge. A significant deal if the timing aligns.
Novaform vs Competing Memory Foam
Novaform competes directly with Tempur-Pedic, Purple, and Casper at a fraction of the price. The main trade-off is that Novaform isn’t available outside Costco, so if you need warranty service, you deal through Costco. Given Costco’s excellent service reputation, this is generally not a concern.
