Quick answer: Helix mattresses purchased after February 1, 2025 carry a limited lifetime warranty covering visible sag over 1.5 inches. The first 10 years are full coverage; years 11 and beyond are prorated. Older purchases use the previous 15- or 25-year terms.

Helix Warranty — Explained
Helix changed its warranty in 2025. Mattresses bought after February 1, 2025 get a limited lifetime warranty for the original purchaser in the U.S. or Canada. Beds bought before that date fall under the older structure — 15 years for standard models and up to 25 years for Luxe — so your purchase date decides which terms apply.
Key Terms (what we could verify)
| Item | Detail |
|---|---|
| Length | Lifetime if bought after 02/01/2025; 15–25 years if before |
| Sag threshold | Visible indentation greater than 1.5 inches (current policy) |
| Proration | Years 1–10 full; 11–15 = 50%; 16–20 = 60%; 21+ = 75% of retail |
| Voids coverage | Removed cover; slats over 5.5 inches apart (9 inches for Kids) |
How to File / What to Do
File through Helix's official warranty or support page with proof of purchase and photos. Confirm your purchase date first, since it determines your terms. Document sag with the bed empty using a taut string, and photograph your base — slats wider than 5.5 inches (9 inches on Kids models) count as improper support and can deny the claim. Never remove the cover; doing so voids the warranty automatically.
Common Problems Owners Report
Owners with older mattresses are sometimes surprised the new lifetime terms don't apply retroactively. Others run into the proration math after year 10, or have claims denied over slat spacing. The cover-removal void clause also catches people who try to wash or swap the cover.
The Saatva Comparison
Saatva offers a lifetime warranty with the same 1.5-inch sag standard, plus a 365-night trial and free white-glove delivery and setup. Where Helix prorates replacements after year 10, Saatva's longer trial lets you settle the comfort question within the first year for a $99 return fee.

Bottom Line
Helix's newer lifetime warranty is a real upgrade, but it only applies to beds bought after February 1, 2025, and prorates after a decade. Check your purchase date, keep the cover on, and use a base with tight slat spacing.
Bottom line: Helix covers sag over 1.5 inches — lifetime if bought after Feb 2025, prorated past year 10, voided if you remove the cover.
