Made with the same one-of-kind technology found in our mattresses, our adapt topper is built with three inches of revolutionary material for an extra soft feel coupled with premium support. Unlike ordinary memory foam, Tempur material continuously conforms to your unique shape for truly personalized comfort and support. Perfect for improving the comfort of any sleep surface, the adapt topper makes it easier than ever to experience the unmatched comfort and support of Tempur-Pedic sleep. Humid nights? No problem. The removable, washable cover features a breathable, moisture-wicking fabric so you can sleep soundly no matter where you rest your head at night. Plus, the cover is hypoallergenic, featuring surface-guard technology that protects against common allergens such as dust-mite dander and mold to keep your topper feeling fresh. Stay tight corner straps create a secure, non-slip application on your mattress, keeping your topper in place night after night.
