It's a beautiful mattress on many different levels. The top layer of the mattress is designed to dissipate body heat. Just below that is our Bio Foam memory foam layer that instantly conforms to your body. Three additional layers provide the support you need for great, restorative sleep. A significant feature of this mattress is our PRESSURE RELIEF SYSTEM that you can actually feel when you lay on the mattress. Special areas inside the mattress are more pliable and accommodating to the areas of your body that create pressure points: your shoulders and hips. Top layer of breathable 1" Cool Foam and a micro fiber layer for added comfort and less heat build up. Second layer of 2" heat sensitive memory foam with Green Tea, Charcoal and Natural Castor Oil which minimizes the use of petrol based chemical oils, working to eliminate chemical odor and to minimize growth of bacteria in a natural way. Third layer of 3" pressure relief foam eliminates pressure points. Fourth layer of 6" high density foam to provide long lasting durability and stability. Real Mattress in a Box embraces the idea of "Sleep Green" so that the comfort of your sleep environment is balanced with ingredients that are safer for you and the environment we all share. Natural Green Tea Extract is a natural odor protectant. Real bamboo fibers used for the construction of the cover. California King 76"x84"x12".
