Abstract
A plurality of pairs of inflatable air cells disposed on opposite sides of a longitudinal axis are arranged along the length of a bed. Each of the air cells extends substantially transverse to the longitudinal axis and are supplied with air so that cells on alternate sides are inflated while simultaneously the cells on the other side are deflated. An upper layer of a resinous foam pad is provided on which the patient lies. The pad is provided with a groove along its longitudinal axis for comfort of the patient. The assembly is completed by a covering having an upper sheet member removably attached to a lower sheet member so that when soiled it may be easily removed.
