Rest assured that high-density quilt foam provides the comforting feel you love. You can also sleep better than ever as you rise to new heights, and get a head and foot massage, with the adjustable power base. With the touch of a button on the wireless remote control, position the mattress to eliminate pressure points for a comfortable sleep. Two convenient USB ports are available for connecting electronics.
