With the Hybrid 1100 mattress and adjustable base, you have endless possibilities for restful sleep. Feel the support of a truly traditional coil mattress which contours to your body for a comforting feel. High-density foam provides the firmness you love. Convoluted comfort foam provides added air flow, keeping you cool and comfortable while alleviating aches and pains. This mattress arrives in a box for quick and easy setup. Simply remove the plastic wrap and unroll. The adjustable base rises to new heights and you get the sleep you've always dreamed of with a power base offering adjustable head and foot positioning. With the touch of a button, adjust the mattress to eliminate pressure points for a comfortable sleep. Raise your legs to increase blood circulation and relieve pressure on your lower back. Raise your upper body so you can sit up in bed or sleep in a partially inclined position (helpful for people who snore or experience acid reflux). Two convenient USB ports are available for connecting electronics.
