YAWNDER MATTRESS REVIEW
Review method: This guide examines Novaform’s and Costco’s published information for the 14-inch Legacy Premier Support Hybrid. It does not report a hands-on test of this exact model. Price and purchase terms can change.
Our Verdict
The Novaform Legacy Premier Support Hybrid is a candidate for Costco shoppers who want a substantial euro-top mattress with a choice of Medium or Firm. Its foam comfort system sits above a zoned innerspring unit, and the listing includes white-glove delivery subject to location and eligibility. It is a different design from Novaform’s all-foam models.
Choose the feel carefully: the Firm version may be too hard for some side sleepers, while the Medium is not guaranteed to suit everyone. We have not tested this exact model, so we cannot independently score its cooling, pressure relief, edge support or durability.

Who Should Consider It?
- Costco shoppers who prefer a coil hybrid over an all-foam mattress.
- People who want to choose between Medium and Firm.
- Buyers who appreciate delivery to the room and eligible old-mattress removal.
- Shoppers who have room for a 14-inch mattress and appropriate deep-pocket sheets.
Who Might Prefer Something Else?
- People who prefer a very plush, deeply conforming surface.
- Shoppers seeking latex as a natural material: “latex-like” describes foam feel in the listing, not necessarily latex content.
- Anyone expecting powered cooling or a guaranteed overnight temperature.
- Buyers who cannot accommodate the height or who want a lower-profile bed.
Construction: Medium vs. Firm
Costco describes a cool quilted euro top, foam comfort layers, zoned back-support foam, a six-inch zoned innerspring system, a HighRise edge perimeter and base foam. Its Medium and Firm diagrams list different foam thicknesses and layer compositions. Confirm the selected version rather than assuming the two feel alike.
Novaform identifies its foam as CertiPUR-US certified and made in the USA, and says the foam and cover are fiberglass-free. Certification applies to qualifying foam; it is not proof that every component or the finished mattress is organic. “Latex-like support foam” is the retailer’s description of feel; ask the manufacturer about exact materials if needed.
The zoned components are intended to change support across the bed. Whether those zones fit your body depends on your height, proportions and sleep position.
Which Firmness Fits?
Medium
Consider Medium if you want some cushioning, sleep in multiple positions or are comparing with a partner. Side sleepers should check for pressure at the shoulder and hip; a medium label can feel firm to someone who compresses the layers less.
Firm
Firm is a starting point for people who prefer a sturdier surface, including some back and stomach sleepers. Check that the hips feel supported and that pressure points remain comfortable. Firmness and support are related but not interchangeable.
Combination sleepers should roll between usual positions and decide whether the foam response feels comfortable. We have not measured this model’s response time.
Dimensions, weight and setup
Novaform lists both queen feels at 60 by 80 by 14 inches, but their weights differ: approximately 111.6 pounds for Medium and 124.8 pounds for Firm. King weights are listed at 140.9 and 155.9 pounds respectively. Check the selected feel, total bed height and fitted-sheet pocket depth; use the manufacturer’s current measurements and instructions when ordering.
Novaform says the mattress arrives compressed and can take up to 48 hours to fully expand. Costco’s listing includes delivery to the room of choice, setup, packaging removal and eligible old mattress and foundation haul-away, subject to delivery-area and condition restrictions. Confirm the service at checkout. Costco identifies this 14-inch model as item 1847133.
What Costco members report
On October 29, 2026, Costco displayed 4.3 out of 5 stars from 1,239 reviews, including 832 five-star and 78 one-star ratings. Some visible reviewers liked the firm feel; others reported issues with size or early sagging. These individual accounts can reflect different sizes or firmness choices and are not Yawnder test results.
Cooling, Motion and Edge Support
A cool-to-the-touch cover and airflow-oriented materials are passive features. They do not actively cool the bed, and initial surface temperature is not the same as an overnight measurement. Test with your usual sheets and protector.
The listing describes an edge perimeter and zoned coils. Sit and lie near the edge to assess stability. If sharing, have one partner turn over while the other lies still. Specifications do not establish a Yawnder motion or edge-support score.
Legacy Premier vs. Other Novaform Mattresses
The Legacy Premier Support Hybrid uses coils; the Novaform all-foam models discussed in our Novaform mattress review use a foam support core. Different model names and generations can have different materials, firmness and retailer terms. For another coil model, see our ComfortGrande Advanced Hybrid review.
Costco also lists a separate 16-inch Legacy Elite Premier Hybrid Euro Top. Do not assume it is the same mattress or apply the 14-inch model’s layer descriptions to it. Compare the exact height, feel, price and delivery terms before ordering.
Legacy Premier vs. ComfortGrande Advanced Hybrid
| Feature | Legacy Premier Support | ComfortGrande Advanced Hybrid |
|---|---|---|
| Height | 14 inches | 14 inches |
| Firmness | Medium or Firm | Medium |
| Construction | Euro top, foam and zoned innerspring | Quilted cover, gel memory foam and coils |
| Costco delivery | White-glove setup and eligible haul-away | Boxed threshold delivery; setup costs extra |
Listings and delivery eligibility can change; verify your exact size, selected feel, service and checkout price.
Costco Price, Delivery, Returns and Warranty
The accessible Costco listing did not show a reliable price when checked October 27, 2026. Sign in, select the exact size and feel, and enter your delivery location for the current total and availability. A foundation is a separate consideration; verify what the selected listing includes.
Costco describes white-glove delivery to the room, setup, packaging removal and eligible haul-away, with service-area and condition restrictions. Additional shipping charges may apply in some locations. California customers who do not receive haul-away at delivery should check Costco’s listing for the current request process.
Costco references its satisfaction guarantee, subject to limitations. Confirm the actual return process and model-specific restrictions with Costco rather than assuming a manufacturer’s direct trial applies. Novaform advertises a 20-year limited warranty. Review the written warranty, foundation and airflow requirements, and claim procedures; warranty length does not guarantee comfort for 20 years.
Frequently Asked Questions
Is the Legacy Premier Support an all-foam mattress?
No. It has foam comfort layers above an innerspring support unit.
Is the 14-inch model the same as the 16-inch Legacy Elite?
No. Costco lists them as separate models. Confirm the exact product, height and specifications.
Does it contain latex?
The listing calls some support foam “latex-like.” That wording alone does not establish latex content; ask Novaform for the current material details.
Does Costco remove the old mattress?
The listing describes eligible haul-away with white-glove delivery, subject to location and condition restrictions. Confirm your order’s service at checkout.
Is it actively cooled?
No powered cooling system is described. The cover and airflow features are passive.
Our Final Take
The 14-inch Legacy Premier Support Hybrid is worth comparing if you want a euro-top coil mattress with two feel choices and Costco’s delivery package. Check the current price, select the exact firmness and confirm the seller’s return and foundation terms.
