An air movement overlay system including a pair of parallel main rolling chambers arranged under the patient's torso. Auxiliary rolling chambers overlie each main rolling chamber. Constant pressure inflation head rest, leg separation chamber, and outrigger chambers are provided. The system is automatically controlled to establish the patient alternately in roll right and roll left positions, interspersed with neutral positions. In preparation for rolling, both main rolling chambers are inflated to a pressure of at least about 65% of the maximum main rolling chamber inflation pressure. The main rolling chambers are spaced apart and connected by a central uninflated web.
