SensAir™ adjustable number beds use air as the support core and feature independent adjustability for each side of the bed. Both you and your partner can enjoy personalized comfort and support so you can Sleep Better Together. Advanced computerized technology allows you to precisely adjust your comfort and support levels from soft to firm in single digit increments from 1 to 100. SensAir™ is the only air bed manufacturer allows for this remarkable degree of precise adjustability. And Unlike the popular Sleep Number® Bed by Select Comfort®*, which only offers dual zone beds, SensAir™ offers six-zone adjustable sleep systems. If you need extra support because of back or hip pain, the center air chamber on each side of the bed can be adjusted separately from the head and foot.
