This 14" thick mattress has a tight top and low motion transfer, so it's designed to let you stay asleep, even if your partner tosses and turns. Four layers of memory foam and innerspring give it a plush feeling with a breathable, moisture-wicking design that helps keep you cool while sleeping. It also features edge support to ensure you can sleep on any spot without the mattress sagging, and it includes a polyester cover to retain mattress freshness. Compatible with adjustable bases (frame and box spring sold separately), it arrives at your doorstep packed in a box and is backed by a 10-year manufacturer's warranty.
