9 Best Costco Mattresses of 2026

Tempur-Pedic ranks first because it scores highest on our performance measure, and pressure relief is the reason many shoppers look for it in a Costco warehouse. The TEMPUR-Adapt is the brand's own entry model: a 4cm TEMPUR-Material comfort layer sits on a 4cm TEMPUR-Material support layer, under a cool-to-the-touch cover, in an 11-inch profile. It comes as an all-foam Medium or a Medium Hybrid with coils. The queen cost $2,099 on Tempur-Pedic's US store when we checked, $200 off the $2,299 list price. Costco does not stock the Adapt by that name; its Tempur-Pedic listings use Costco models such as the Supreme 11.5 inch, so compare layer heights and feel rather than names, and use the Adapt price as a reference point. The main trade-offs are a single medium feel, a memory foam surface that some people find warm, and a 90-night trial on direct orders.

Leesa Original takes second place on balance: solid performance, an easy medium feel and a strong value score. Leesa builds it with 2 inches of open-cell GreenFlex Foam, a plant-based foam meant to let heat escape, over 2 inches of 3-lb memory foam and a 6-inch high-density foam core, for a 10-inch total. The queen cost $999 on Leesa's US store when we checked, down from $1,332, and a Cooling Quilt Top costs $185 more. Leesa lists GREENGUARD Gold certification, CertiPUR-US certified foams and a fiberglass-free build. On direct orders Leesa gives a 365-night trial and a limited lifetime warranty, the longest terms here, but Costco sets its own delivery and return rules, so confirm which terms apply to a Costco order. The weak points are the lack of coils in the base model and a contouring feel that stomach sleepers who like a firm surface may find too soft.

Sealy Posturepedic ranks third and has the strongest value score of the coil beds here. Sealy's own Posturepedic Spring is a 13-inch mattress with ultra-responsive springs and memory foam, designed so you sleep on top of the bed rather than in it, plus a Center Support layer that reinforces the middle where the body is heaviest. The queen cost $799 on Sealy.com when we checked, with the Posturepedic Hybrid, which Sealy says has over two times more specialty foams, at $999. A pillow top adds $200. Costco sells Sealy under its own model names, such as the Posturepedic Pro line, so treat these as reference specs and prices and check coil type, height and comfort layers on the Costco listing. The limits: less pressure relief than the memory foam beds above, a medium feel on the spring version, and a 90-night trial when you buy direct.

Stearns & Foster Lux Estate places fourth with the second-highest performance score, held back by its price. It uses patented IntelliCoil coil-in-coil innersprings, an extra layer of TEMPUR-Indulge Memory Foam compared with the base Estate, a gel foam quilt and a cool-to-the-touch cover. The queen cost $2,599 on the Stearns & Foster US store when we checked, $400 off its $2,999 list price, and direct orders include white glove delivery. Costco carries the Stearns & Foster brand and also sells a Kirkland Signature mattress made by Stearns & Foster, so check both if you like the feel. Costco's own listing is the place to confirm specs and price for those models, since the brand site does not cover them. The trade-offs are cost, a 90-night trial on direct orders, and a heavy build that is harder to move than a boxed foam bed.

Beautyrest Level Two Hybrid ranks fifth, a balanced hybrid for couples. Beautyrest builds it on 875 Density Pocketed Coil Technology, which it says gives individualized support and motion separation, under ActiveResponse MAX High Density Memory Foam and an InfiniCool cool-to-the-touch surface, for a 12-inch height in a medium firm feel. Beautyrest's US store showed $1,099 when we checked, but the page did not tie that price to a size, so treat it as a starting price. Direct orders include a 100-night trial, free shipping and returns, white glove delivery, free mattress removal and a 10-year warranty. Costco lists Beautyrest among its mattress brands, though its warehouse models may use different names and layer stacks. The limits are a single feel, the size question on price, and a memory foam top that is softer than a classic quilted innerspring like the Beautyrest Level One.

Casper The One ranks seventh as the simple boxed foam choice. It is an 11-inch mattress with three foam layers, a Cozy Cover and breathable foams, set at a responsive, medium-firm feel; a Cloud One version with a plusher top costs $180 more. The queen cost $799 on Casper's US store when we checked, 30% off a $1,149 comparison value, and direct orders include a 100-night trial and a 10-year limited warranty. Costco lists Casper among its mattress brands, which makes it a familiar name for members who want an easy online purchase. It scores lower on performance than Leesa Original because it has fewer documented comfort features and no coils, and the $799 is a sale price that can move. For a firmer foam bed at a lower price, Tuft & Needle Original is cheaper.

Purple Mattress ranks sixth, the pick for people who want something other than memory foam. Instead of a foam comfort layer it uses a 2-inch GelFlex Grid over comfort foam, which Purple says balances support and pressure relief for stomach, back, side and combination sleepers. The feel is medium-firm and responsive. The queen cost $1,299 on Purple's US store when we checked, $300 off $1,599, with a 100-night trial and a 10-year warranty on direct orders. Costco lists Purple among its brands, so the model may appear online or in some warehouses, but stock varies, and Purple notes that not every bed frame is suitable. The grid surface is the reason to buy it and also the main risk, because it feels unlike anything else on this list. At $1,299 it also costs more than the Leesa and Casper foam beds.

Tuft & Needle Original ranks eighth overall but is the cheapest bed here, with one of the top value scores. It is a 12-inch all-foam mattress that puts T&N Adaptive foam over Support Foam and a durable Base Foam, and the brand describes it as its firmest feel. The foams are CertiPUR-US certified and the mattress is Greenguard Gold certified. The queen cost $559.20 on Tuft & Needle's US store when we checked, 20% off, with free shipping, free returns and a 100-night trial on direct orders. Costco lists Tuft & Needle among its mattress brands, so members may find it online. The firm surface is the main reason to choose it and the main reason not to: side sleepers will likely find it too hard at the shoulder. It also has the fewest comfort features here, and its product page does not state the warranty length.

Sleep Number ComfortMode ranks ninth, a specialist pick rather than a default. Its point is adjustable firmness on each side of the bed, so two people with different preferences can share a queen without compromise, and either can change the setting later. The 10-inch ComfortMode adds joint and pressure point relief and built-in cooling materials; the 11-inch ComfortMode Lux targets hip relief and costs more. The queen started at $1,799.10 on Sleep Number's US store when we checked, against a $1,999 regular price, and direct orders include a 100-night trial and a 10-year limited warranty, with full coverage for the first 2 years. Costco lists Sleep Number among its mattress brands. It scores lowest on ease of use because an adjustable air bed has more parts to set up and look after than a standard mattress, and its value score reflects a high price for a 10-inch bed.
