Generally speaking, Amerisleep offers a 20-year warranty. It’s split into a 10-year full replacement warranty and a second 10-year prorated warranty.
The warranty cover manufacture defects, indentations greater than 1″ (excluding corners and edges), and excessive sagging (assuming the mattress has been used with a suitable bed frame).
Note: This warranty is void if you end up selling or giving the mattress away to a secondary owner.
