Comfort When it comes to purchasing a mattress the most important thing to consider is comfort. The Sleep Master 10-inch Gel memory foam mattress contours to your body to provide you a customized level of support and comfort. The top layer of the mattress is a 2.5-inch layer of Gel foam, which is designed to keep your body cool and provide a soft comfortable surface. Directly underneath the top layer is a 3-inch pressure relief foam made to minimize pressure points particularly at the shoulders, hips and feet. The bottom layer is a 4.5-inch high-density foam. This layer acts as the support for the mattress to give you a firm and satisfying night sleep. Temperature Temperature can play a big part in how well you sleep at night. Your body naturally releases heat as a way to prep you to fall asleep. Memory foam mattresses have been known to tramp heat hampering this natural process. We had already made tremendous strides in this a and now we introduce to you the Sleep Master Gel memory foam mattress. It is an open cell memory foam with thousands of gel beads for better air flow movement while still providing the customized level of support you accustomed to with memory foam. Environment Sleep Master embraces the idea of "Sleep Green" so that the comfort of your sleep environment is balanced with ingredients that safer for you and the environment. We use Bio Foam in all our mattresses, which is made with natural seed oil and minimizes the use of petrol based chemical oils.
