by The Novaform 14" Legacy Premier Support Hybrid is Costco's flagship hybrid: 14 inches tall, zoned pocket coils, LURAlux support foam, CertiPUR-US certified, fiberglass-free, and backed by a 20-year warranty plus Costco's unlimited return policy. It delivers genuine hybrid performance at a $899–$1,199 price that undercuts comparable online mattresses by 30 to 40 percent. If you need a comparable online alternative with a formal sleep trial, the Amerisleep AS3 is worth comparing.

Construction breakdown: what the 6 layers actually do
The Legacy Premier stacks six layers into its 14-inch profile. The cool-touch euro top uses graphite-infused fiber that keeps the surface noticeably cooler than untreated polyester. Below that, LURAlux foam provides a responsive transition — it pushes back faster than traditional memory foam, reducing the stuck-in-the-mattress feeling that side sleepers dislike. The zoned back-lift foam layer targets lumbar support specifically, with firmer sections under the lower back and softer sections under the shoulders.
The coil unit uses zoned innerspring construction — denser gauge coils in the center third to resist pelvis sag, lighter gauge at the periphery for shoulder contouring. Queens ship with approximately 868 coils. The HighRise foam perimeter provides edge support around the entire base, though foam-only edges compress more than perimeter-coil systems under sitting weight. The dense base foam closes out the stack and keeps the coils stable over time.
Who the Novaform 14" Legacy Premier is actually for
The mattress fits combination and back sleepers between 130 and 230 lb best. The medium firmness version registers around a 6/10 — firm enough to support lumbar curvature for back sleeping, soft enough to relieve shoulder pressure during side sleeping. Strict side sleepers under 130 lb may find both firmness options slightly firm at the shoulder; strict stomach sleepers over 180 lb may find the comfort layers too compressible for hip alignment.
| Sleep position | Body weight | Fit |
|---|---|---|
| Side | 130–230 lb | Good (Medium) |
| Back | 130–230 lb | Very good |
| Stomach | Under 180 lb | Decent (Firm version preferred) |
| Stomach | 180+ lb | Not ideal |
| Combination | Any | Good to very good |
The Costco return advantage
Costco's lifetime satisfaction guarantee applies to mattresses with no break-in requirement and no fixed return window. You can return a Novaform after one night or after two years and receive a full refund. No competitor matches this policy. Saatva offers 365 nights but charges $99 for pickup. Most bed-in-a-box brands offer 100 nights with mandatory break-in periods of 30 nights before return eligibility kicks in.
The practical catch is logistics: returns require a trip to a Costco warehouse or a paid pickup for most locations. For buyers in metro areas, this is workable. For rural buyers without easy warehouse access, a formal doorstep-return trial from an online brand is functionally simpler.
Off-gassing: the main drawback
Third-party testing places the Novaform Legacy Premier's off-gassing window at 14 to 16 days — more than twice the 7-day average for comparable hybrids. The compressed-in-box shipping concentrates the off-gassing relative to mattresses that ship flat and uncompressed. Allow the mattress to air out in a ventilated room for two to three weeks before extended sleep. The smell is not a safety risk (the foam is CertiPUR-US certified for VOC limits), but it is noticeable and may cause headaches for chemically sensitive sleepers if skipped.
Novaform vs other Costco hybrids
| Costco hybrid | Height | Queen price | Best for |
|---|---|---|---|
| Novaform 14" Legacy Premier | 14" | $899–$1,199 | Combination, back, 130–230 lb |
| Novaform Comfort Grande Plus | 14" | ~$699 | Side sleepers, softer feel |
| ComfortLuxe Gel (all-foam) | 12" | ~$399 | Guest rooms, lighter sleepers |
| Sealy Cocoon Hybrid (Costco) | 11" | ~$899 | Hot back sleepers |
The Novaform 14" Legacy Premier Support Hybrid is a genuine value hybrid at $899–$1,199. Zoned coils, LURAlux foam, fiberglass-free construction, and Costco's unbeatable return guarantee make it a credible primary-bed purchase. The only meaningful drawbacks are the 14-16 day off-gassing window and foam-only edge support. For Costco members, it rates 8.1/10.
Amerisleep AS3
8.9/10
- Formal 100-night sleep trial with doorstep pickup — no Costco run required
- HIVE 5-zone support targets lumbar zone directly
- Partially plant-based Bio-Pur foam, CertiPUR-US certified
- 20-year warranty, made in USA
- Financing available (Klarna 0% APR)
- All-foam construction — slightly less responsive than coil hybrid
- Softer edges than the Novaform's HighRise perimeter
- Sleepers over 230 lb may prefer the firmer AS5 Hybrid instead
If you are not a Costco member or want a formal doorstep sleep trial, the Amerisleep AS3 is the strongest online alternative at a similar price. Its HIVE lumbar zoning and 100-night trial make the risk comparable to Costco's return guarantee.
Frequently asked questions
How much does the Novaform 14" Legacy Premier Support Hybrid cost?
Novaform lists the Legacy Premier at $899.99 to $1,199.99 for queen depending on firmness and current promotions. Check Costco.com or your local warehouse for the current price — Costco pricing fluctuates with member events.
Does the Novaform 14" Legacy Premier contain fiberglass?
No. Novaform lists both the foam and the cover as fiberglass-free. The foam is CertiPUR-US certified. Older Innocor production (pre-2022) used different materials, so this applies to current production only.
How long does the off-gassing last?
Third-party testing shows 14 to 16 days for the Legacy Premier — more than twice the hybrid average. Allow two to three weeks of ventilation in a well-aired room before sleeping on it. The foam meets CertiPUR-US VOC limits so it is not a safety hazard, but the smell is noticeable.
Can I return it after several months?
Yes. Costco's satisfaction guarantee has no fixed window and no break-in requirement. You can return a Novaform mattress after any amount of time for a full refund. Returns require either a warehouse trip or paid pickup service.
Novaform Legacy Premier vs Amerisleep AS3: which is better?
They serve different buyers. Novaform wins on price, hybrid construction, and Costco's unlimited return policy for existing Costco members. Amerisleep AS3 wins on formal doorstep return logistics, HIVE lumbar zoning, and the flexibility of buying without a Costco membership. If budget and Costco membership align, Novaform gives more construction for the money. If you want an online sleep trial with simple returns, AS3 is the stronger pick.
Is the Novaform Legacy Premier worth it at $899–$1,199?
For Costco members, yes. The hybrid construction, 14-inch profile, zoned coils, fiberglass-free materials, and 20-year warranty would cost $300 to $500 more from most online-only brands. The Costco return guarantee removes the purchase risk entirely.
