This is the optimal position needed to achieve the deepest, most restorative levels of sleep possible. For additional relaxing benefits, the base include a 3-speed dual massage for head and foot areas. The wireless remote and simplified touch-key configuration allow you to adjust the head tilt and feet lift to your desired position. Enjoy customized comfort as you read, work, watch TV, sleep or relax in bed. For additional convenience, there are USB charging ports for your smart phone or tablet. A steel retainer bar at the foot of the mattress keeps your mattress in place. This 15" high adjustable foundation fits easily in most standard bed frames.
