by Quick answer: Simmons makes Beautyrest mattresses, typically with a 10-year limited warranty. Your sag threshold and proration depend on the warranty code on the law tag. After an initial full-coverage period, later claims are prorated, and you pay transport.

Simmons's Warranty Explained
Simmons is the maker behind Beautyrest, and warranty service runs through Beautyrest/Simmons. Most mattresses carry a 10-year limited warranty, but the exact terms are tied to a warranty code printed on the white law label. That code sets both your sag threshold and how proration applies, so the label is the first thing to check.
Key Terms (what we could verify)
| Item | Detail |
|---|---|
| Warranty length | Commonly 10 years, prorated after an initial full-coverage period (varies by code) |
| Sag threshold covered | 1.5 inches for some codes, 0.75 inch for others — determined by your law-tag code |
| Who pays transport | You. Except in California, transportation, inspection, and removal costs are excluded |
| Common exclusions | Normal softening, stains/soiling, unsanitary condition, and damage from an unsupportive frame |
| How to start | brand's official warranty page |
How to File / What to Do
First, rule out a foundation problem and rotate the mattress, since improper support causes sag that isn't covered. Gather your original bill of sale plus the model and law labels, which are required to validate the claim. Then file through your original dealer, or use Beautyrest's official warranty page and online form if the dealer is unavailable. Be aware an inspection fee and a delivery fee for any replacement may apply.
Common Problems Owners Report
Owners often discover their sag doesn't meet the code's threshold once measured without body weight. The proration is another surprise: a 10-year warranty that fails at year 5 may only be covered around 50%, with the owner paying the rest plus delivery. Any stain or unsanitary condition can void service entirely.
The Saatva Comparison
Saatva's Saatva Classic skips the law-tag code system with a straightforward lifetime warranty. A 365-night trial, flat $99 returns, and free white-glove delivery mean fewer fees stacked onto a claim. You don't decode a threshold or pay an inspection fee just to learn whether you qualify.

Bottom Line
Simmons/Beautyrest coverage is real but code-dependent and prorated, with the owner paying transport and possible fees. Read your law tag, use a rigid supportive frame, and protect against stains from day one.
Bottom line: Beautyrest covers code-defined sag for about 10 years, but proration and fees mean later claims aren't free.
