Sealy Warranty — Explained
Sealy backs its mattresses with a 10-year limited warranty in most cases, though exact terms depend on the model and purchase date printed on your law tag. The warranty applies to the original purchaser who bought from an authorized U.S. dealer, and it covers manufacturing defects and qualifying sag — not comfort preference.
Key Terms (what we could verify)
| Item | Detail |
|---|---|
| Length | Typically 10 years (confirm via your law tag's Warranty Code) |
| Sag threshold | Over 1.5 inches for innerspring/latex; about 0.75 inch for memory foam |
| Transport costs | Paid by the purchaser |
| Voids coverage | Wrong foundation/frame, stains, burns, cuts, misuse |
How to File / What to Do
File through Sealy's official warranty page or your authorized dealer. You'll need the original receipt and the law label from the mattress. Measure sag with the bed empty: pin a taut string across the surface and measure the deepest point on flat fabric without pushing in. Note that you cover any transportation costs for repair or replacement.
Common Problems Owners Report
The biggest gap is the "sagging gap." Sealy requires more than 1.5 inches of sag, yet a dip of 1.0 to 1.4 inches can already cause back pain and poor sleep without qualifying. The other frequent denial reason is foundation: using the wrong base or frame can void the warranty outright.
The Saatva Comparison
Saatva offers a lifetime warranty rather than 10 years, plus a 365-night trial with free white-glove delivery. The trial is the real difference: you can decide a Sealy is too firm or too soft within a year and return it for $99, instead of waiting a decade hoping sag crosses 1.5 inches.

Bottom Line
Sealy's warranty is a standard 10-year limited policy: real defect and sag coverage, but with a strict 1.5-inch bar and firm foundation rules. Check your law tag for the exact code, and keep your receipt and proper base in place.
Bottom line: Sealy covers innerspring sag over 1.5 inches for 10 years, but you pay shipping and a wrong frame can void it.
