This 8" mattress has a tight top, edge support, and low-motion transfer, so it's designed to let you stay asleep, even if you or your partner toss and turn. With layers of gel memory foam, this mattress offers a firm feel, so it's great for those who need plenty of support to sleep. It also arrives compressed inside a box, so we recommend giving it time to expand to its full size. Best of all, it's backed by a 10-year manufacturer's warranty. Because this mattress includes a non-removable cover, we recommend adding a topper to retain mattress freshness and mitigate stains.
