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. Three layers of memory foam have a medium firmness and a breathable design that helps keep you cool while you sleep. It includes a stain- and fade-resistant polyester cover to retain mattress freshness, and it's a white hue that won't peek through lightly colored sheets. This mattress is also compatible with an adjustable bed base (base and frame sold separately). It arrives at your doorstep packed in a box and is backed by a 10-year manufacturer's warranty.
