Allswell's Warranty Explained
Allswell is a Walmart-owned brand, and its mattresses come with a 10-year limited warranty from the purchase date. It covers manufacturing and material defects plus qualifying sag, but excludes normal wear and the gradual softening of foam. The warranty is non-transferable and applies only to the original buyer.
Key Terms (what we could verify)

How to File / What to Do
You'll need original proof of purchase plus photos of the mattress, the law label, and the foundation you're using. For sag, document depth with a straightedge and ruler. File through Allswell's official warranty channel; note that mattresses bought through Walmart may fall under different terms than those bought on the Allswell site, so confirm which applies to your order.
Common Problems Owners Report
The foundation and law-tag rules trip people up: an unsupportive base voids coverage, and removing the law tag voids it entirely. A less obvious one is that using a heating pad or electric blanket voids the warranty. Normal body impressions under the threshold are expected and aren't claimable.
The Saatva Comparison
Saatva's Saatva Classic offers a lifetime warranty rather than 10 years, with a 365-night trial, flat $99 returns, and free white-glove delivery including old-mattress removal. There's no electric-blanket clause or prorated-refund math, and the longer term gives more protection over the life of the bed.

Bottom Line
Allswell's 10-year warranty is fair for a value brand, but the foundation, law-tag, and electric-blanket rules decide most claims. Keep your receipt, leave the law tag on, and use a solid supportive base.
Bottom line: Allswell covers sag over 1.5 inches for 10 years, but improper support, a removed law tag, or an electric blanket will void it.
