Costco Queen Mattress Deals Fact-Check: Are These Discounts Really Worth It?
The crown jewel of warehouse bedding aisles is the Kirkland Signature mattress built by Stearns & Foster. Retailing for roughly $999.99 to $1,199.99 in queen sizing, and occasionally dipping toward $849.99 during major promotions, it commands serious attention from shoppers seeking traditional high-end construction without showroom markups.
Underneath the quilted exterior, the mattress uses an IntelliCoil dual-stage innerspring layout, a high-density encasement border, and multiple layers of proprietary memory foam. In standard department store environments, equivalent Stearns & Foster Studio or Estate series mattresses command between $1,699 and $2,199.
| Queen Mattress Model | Core Construction | Typical Promotional Price | Traditional Retail Equivalent |
|---|---|---|---|
| Kirkland Signature by Stearns & Foster | IntelliCoil Innerspring + Gel Foam (14.5-inch) | $849.99, $999.99 | $1,699, $2,199 |
| Sealy Posturepedic Carver / Mount Auburn | Response Pro Encased Coils + Target Support | $499.99, $599.99 | $899, $1,099 |
| Novaform ComfortGrande 14" | Tri-layer All-Foam with Gel Memory Comfort | $399.99, $499.99 | $799, $950 |
| GhostBed Classic 11" | Latex + Gel Memory Foam Layered Core | $499.99, $629.99 | $945, $1,195 |
There are structural compromises, however. The Kirkland variant features slightly less micro-coil perimeter reinforcement than flagship boutique units, and it comes solely in a medium-firm profile. If you prefer plush pillow-tops or ultra-firm slabs, the Kirkland model will not accommodate you. But for back and combination sleepers wanting a dense, durable coil structure, it is arguably the cleanest value proposition on the warehouse floor.
