Unlike traditional mattresses, which are made from metal coils and springs, The Sleep Number Bed by Select Comfort™ uses patented air-chamber technology to provide a gentle cushion of support that can be easily adjusted to each individual's preference for comfort and firmness. The uncomfortable pressure points that can cause tossing and turning are minimized at the simple touch of a button. Clinical studies have shown that the Sleep Number® bed can improve sleep quality and help relieve back pain. Plus, the Sleep Number® bed allows couples to individually adjust each side of the bed to the precise comfort level each partner prefers. Enjoy more deep, restorative sleep on the Sleep Number® bed.
