The TENCEL® cover is a performance fabric like no other, absorbing moisture completely and naturally, creating a cooler and more comfortable sleep. With more breathability than cotton, and a softer hand than silk, TENCEL® can be found anywhere from athletic wear to luxurious bedding. Nothing is dreamier than going to sleep on a bed made with TENCEL® fibers.

Support Info

Our CoolRest™ gel advanced memory foam quickly conforms to your body for pressure relief and support without letting you sink too far into the mattress.

The OkiFirm's graphite foam provides firm support to keep your body in its desired position and help with back and spine alignment without leaving you feeling like you are floating on top of the mattress. Our densest foam layers provide comfortable but solid support with little give to protect from unwanted contouring.
