The Solar 9" Pocket Coil Mattress is a luxurious sleep surface guaranteed to improve the quality of your sleep. Emphasizing the importance of safety while you sleep, the inner components of this mattress are surrounded by two protective fire resistant barriers. The firmness of this tight top have two high density foam layers resting directly beneath it: a 1.18" 22D layer and a .8" 20D layer. These high density foam layers supply cushion-like comfort and evenly distribute your body weight along the surface to reduce stress off of your shoulders and hips.
