The DynaRest Airfloat Plus is a convenient, medical grade air mattress designed with user comfort in mind. The mattress is equipped with a digital air pump and air pressure controls with weight indicators to directly customize the firmness of the mattress. The Airfloat Plus has three settings: static, which is ideal for patient transfers, and alternating, which provides cell inflation for pressure redistribution, and a seat function, which helps relieve pressure when upright.
