Yawnder mattress reviews · October 27, 2026
The Sealy Icon 12-inch Medium Hybrid is a Costco mattress combining gel foam and coils. Its moderate height and medium label make it worth comparing if you want a hybrid without the extra height of many pillow-top models.
Review method: This assessment is based on Costco’s listing and published purchase information. We have not tested this exact model or independently measured its pressure relief, cooling, motion transfer, edge support or durability.
Quick verdict
Consider the Sealy Icon if you want a 12-inch hybrid with a medium-labeled feel and a reinforced coil edge. Compare the exact model and total delivered price before buying. If you need a particularly soft or firm mattress, test alternatives instead of relying on a medium label alone.

Who should consider it?
- Hybrid shoppers: It combines cushioning foam and a coil system. Learn more in our hybrid mattress guide.
- People comparing moderate bed heights: Its listed 12-inch profile may fit a lower setup than a thick Euro-top mattress. Measure your frame and foundation too.
- Costco members: Check the selected size, delivery service and total before ordering.
Look at other options if you prefer all-foam contouring, a very firm surface, or have a specific pressure-relief need that you cannot evaluate before purchase. The medium label is relative and comfort depends on body size and position.
Construction and feel
Costco lists a ComfortLoft cover with cooling fibers and Surface-Guard treatment, SealyCool gel foam, and a DuraFlex coil edge. It calls the mattress a hybrid and describes the feel as medium. The listing does not establish every layer’s thickness or density, so compare the exact SKU instead of applying specifications from another Sealy line.
Side sleepers can assess shoulder and hip cushioning; back and stomach sleepers can check whether their midsection feels supported. These are fitting suggestions, not hands-on findings for this model.
Cooling, edges and motion
SealyChill fibers and gel foam are advertised cooling features, but they do not establish an independently measured overnight temperature. Costco lists 968 encased coils in a queen and says the DuraFlex edge uses additional coils; we have not measured seated edge compression. We also have no model-specific motion-transfer results. Compare these features in person when possible.
What Costco members report
On October 29, 2026, Costco displayed 4.4 out of 5 stars from 3,195 reviews. The visible comments include people pleased with comfort and delivery, alongside reports of uneven expansion or edge concerns. These are individual customer accounts, not Yawnder measurements; review counts and ratings change, and a listing can include multiple sizes.
Dimensions and setup
Costco lists the queen at 60 by 80 by 12 inches and 93 pounds. The king is listed at 76 by 80 by 12 inches and 112 pounds. This model arrives compressed in a box according to the listing, so measure the route to your bedroom and arrange help moving it. Check the combined height of your mattress, frame and foundation, along with the pocket depth of your sheets.
Costco identifies the product as item 1900489. Keep that number handy when checking availability and support; Sealy and Costco sell other similarly named hybrids. Confirm the base requirements in the manufacturer’s current warranty before ordering.
What does CertiPUR-US mean here?
Costco says Sealy foam meets CertiPUR-US standards. The certification applies to qualifying polyurethane foam and its specified emissions and content criteria; it should not be presented as a certification of the entire mattress.
Price, delivery and returns
Costco did not expose a dependable price by size in the inspected listing. Select the size and confirm membership requirements, availability and the full checkout amount. The listing describes boxed doorstep delivery without setup or package removal. Setup is offered for an additional checkout fee and includes packaging and eligible old-mattress removal; availability and delivery charges can vary by location. Costco says California customers may request old-mattress haul-away at delivery even without the setup upgrade. Confirm the current arrangements for your address.
Costco’s merchandise satisfaction guarantee is subject to its terms and exceptions. Confirm how a mattress return or pickup works for your order. A warranty is separate; check the linked manufacturer warranty for duration, covered defects and foundation requirements before ordering.
Frequently asked questions
How firm is the Sealy Icon?
Costco labels this model medium. We have not independently rated it, and perceived firmness varies by sleeper.
Is it all foam?
No. The Icon is a hybrid; its listed features include foam and a coil edge.
Does it come with setup?
The inspected listing describes doorstep delivery and notes that setup may be offered for an additional fee. Confirm current options at checkout.
Does CertiPUR-US certify the whole mattress?
No. The certification concerns eligible polyurethane foam, not all components of the completed bed.
Final recommendation
The Icon is a reasonable candidate for a medium-labeled hybrid with a 12-inch profile. Confirm your full Costco checkout price, delivery and return arrangements and the exact warranty terms before deciding. For another Costco option, read our Serta Perfect Sleeper Elite Hybrid review.
