Queen Pillow Top Hybrid Mattress and 4M Adjustable Base

With Spring Air's Sleep Sense Hybrid Mattress Collection, you get both a independent coils system and layers of Gel Memory Foam so you can benefit from both kinds of mattresses. The Hi / Lo Coil System puts higher profile individually wrapped coils in areas your body curves up (head, waist, Knees) and lower profile coils in areas you need more room (shoulders and hips), allowing for an even greater degree of body forming support. The lower profile coils are topped off with Gel Support Channels for ultimate pressure relief in your hip and shoulders. Layers of Gel Memory Foam give your body a cool sleeping surface as well as pressure relief and firm cushioning.
