ABSTRACT:
A body support such as a bed, operating table or seat has a flexible top sheet secured over the sides and ends of a frame, and resting on a series of parallel resiliently deformable rollers located between the sides of the frame and supported, in turn, by a longitudinally reciprocal substantially horizontal bearer plate, which is driven back and forth causing the rollers to roll back and forth under the top sheet, thus constantly changing the main pressure areas of the body supported by the top sheet.
