The FeelThis plush mattress is all about plush comfort. At the surface, a 1 inch layer of bamboo charcoal infused memory foam is quilted into the cover. Bamboo charcoal is especially good for sensitive skin and has improved thermal regulation. Beneath the top layer is a 3 inch layer of ventilated, gel infused memory foam. This layer helps improve breathability and temperature for a more comfortable sleep climate. Beneath the comfort layers, this mattress has a 10 inch high density foam base for excellent support.The top memory foam layers contour to your natural curves during the night and add plushness to the surface. The memory foam also helps to isolate motion transfer between sleeping partners.All LUCID memory foam is created using open cell technology. This prevents lasting body impressions and creates a more durable foam. Soft, Breathable Cover Made of a cozy TENCEL blend fabric (10 percent TENCEL lyocell, 90 percent polyester), the soft cover creates a breathable air layer at the top of the mattress. Conveniently Shipped for Easy Set UpAfter your new mattress arrives, simply take the package into the right room, remove it from the box and protective wrap, and watch as it expands.
