YAWNDER MATTRESS REVIEW
Review method: This guide evaluates Costco’s published information for the Tempur-Pedic Supreme Medium Hybrid. It does not report a hands-on test of this specific model. Price, availability and seller terms can change.
Our Verdict
The Tempur-Pedic Supreme Medium Hybrid at Costco is a worthwhile candidate if you want the contouring feel associated with TEMPUR material but prefer a mattress with springs. Costco lists this version as 11.5 inches tall with a medium feel, a cool-to-the-touch cover and more than 1,000 innersprings. Its appeal depends on the current delivered price and whether the slower contour of TEMPUR material suits you.
The Supreme Hybrid is a specific Costco model. It should not be assumed to match an older Cloud Supreme or another TEMPUR hybrid sold elsewhere. We have not tested this model and cannot independently score its motion isolation, cooling, edge support or durability.

- Buyers outside the listed delivery area or looking for a specific model available to test locally.
Construction: What Is Inside?
Costco lists TEMPUR comfort and support material above a spring unit, plus a cool-to-the-touch knit cover. The listing describes more than 1,000 premium innersprings, but does not make the coil count for every individual size clear. It does not provide enough detail to establish every layer’s thickness or density. Confirm the selected model’s current specifications with Costco or Tempur-Pedic if those details are important to you.
The spring unit distinguishes the hybrid from an all-foam Supreme. Springs and foam together can affect the overall response, but their presence alone does not tell us precisely how bouncy or supportive this model will feel to a particular sleeper.
Firmness and Sleeping Positions
Costco describes this version as medium. Firmness labels are not standardized and a lighter sleeper may experience the same mattress differently from a heavier sleeper. We have not assigned a Yawnder firmness score to this version.
Side sleepers
Check whether your shoulder and hip can settle without pressure building. TEMPUR material is designed to conform, but how well it relieves pressure depends on your body and the model’s full construction.
Back and stomach sleepers
Back sleepers should look for comfortable contact around the lower back and support under the hips. Stomach sleepers should check whether the hips settle comfortably without excessive sink. A mattress label cannot guarantee alignment or treat pain.
Combination sleepers
Try rolling between your usual positions. If you dislike a slower foam response, that movement check is especially useful before committing.
What Costco members report
On October 29, 2026, Costco displayed an average of 4.5 out of 5 from 2,158 reviews. The listing includes reviews originally posted on configurations with a foundation or adjustable base, so check which setup each reviewer purchased. Customer feedback is not a Yawnder test score and may change.
Dimensions and setup
Costco lists the queen at 60 by 80 by 11.5 inches and 100 pounds; the king is listed at 76 by 80 by 11.5 inches and 164 pounds. Check the combined bed height and fitted-sheet depth, and make sure your existing support meets Tempur-Pedic’s warranty requirements. This mattress-only listing is item 1752286 and does not include a foundation.
The listing estimates 2–4 weeks for delivery. Its white-glove service includes setup, packaging removal and eligible old mattress and box-spring removal. Costco says delivery is unavailable to Alaska, Hawaii and Puerto Rico for this listing; confirm current availability and haul-away conditions for your address.
Cooling, Motion and Edge Support
The cover is marketed as cool to the touch. That is a passive feature, not an active cooling system. Initial surface temperature is not the same as measured overnight cooling, and sheets, protectors and room temperature affect the experience.
If you share a bed, have one person change positions while the other lies still. Sit and lie near the edge to check stability when getting up and using the full surface. We have not measured these features on the Supreme Hybrid.
Supreme Hybrid vs. Supreme All-Foam
Costco separately lists an all-foam Supreme in Medium or Firm and this Medium Hybrid with springs. Choose by the full product name and construction, not just “Supreme.” A hybrid may have a different response from an all-foam design, but trying the exact mattress is the best way to judge which you prefer. Costco also pools some customer reviews across mattress-only, foundation and adjustable-base listings, so check the referenced configuration when reading feedback.
| Feature | Supreme Medium Hybrid | Supreme all-foam |
|---|---|---|
| Construction | TEMPUR materials and springs | Foam construction |
| Listed feel | Medium | Medium or Firm |
| Height | 11.5 inches | 11.5 inches |
Confirm the chosen model, size and current listing before ordering; these are retailer descriptions.
Costco also offers mattress-only and mattress-with-foundation listings. Compare the same size, whether a compatible foundation is included, the delivery package and the final price. Do not apply findings from Yawnder’s older Cloud Supreme Breeze review to the current Costco Supreme Hybrid. Consider the complete bed height when selecting a foundation; our bed-height guide explains what to measure.
Price, Delivery, Returns and Warranty
The accessible Costco page did not display a reliable price when checked October 27, 2026. Sign in and select your size and delivery address for the current price and availability. The mattress-only listing does not include a foundation.
Costco describes white-glove delivery with setup and eligible removal of an old mattress or box spring. It gives an estimated delivery window and excludes some locations. Confirm current scheduling, removal eligibility and any charges for special circumstances at checkout.
Costco refers to its satisfaction guarantee, subject to exceptions and limitations. Confirm the specific return process and any applicable restrictions with Costco; do not assume Tempur-Pedic’s direct trial applies to a Costco purchase. The listing identifies a 10-year non-prorated limited warranty for qualifying defects. Read the manufacturer’s written coverage, foundation requirements and claims process before buying.
Frequently Asked Questions
Is the Costco Supreme Hybrid the same as the Supreme all-foam mattress?
No. The hybrid listing includes springs; Costco’s separate Supreme listing offers all-foam Medium and Firm versions. Check the full listing before ordering.
Does the mattress-only price include a foundation?
No. Costco labels that configuration mattress only. A separate mattress-and-foundation listing may be available.
Is the Supreme Hybrid actively cooled?
No powered cooling system is described. The cover is advertised as cool to the touch.
Is it the same as the old Cloud Supreme Breeze?
Do not assume so. The names refer to different product listings or generations; compare the exact model and current specifications.
Can it help back pain?
Comfort and support are individual, and the mattress is not a proven treatment. Seek medical advice for persistent or worsening pain.
Our Final Take
The Costco Supreme Medium Hybrid offers TEMPUR material over springs in a lower profile than many luxury hybrids. Check the exact configuration, delivered price and written terms, then evaluate its feel in your usual sleeping positions.
