Abstract
A mat assembly is constructed so as to be tilted about a longitudinal axis by means of a pair of inflatable air bags. The mat assembly has an upper air cushion sheet mounted upon a frame, a lower air cushion sheet provided upon the underside of the frame, and a pair of air bags disposed upon the underside of the lower air cushion sheet at right and left thereof as viewed in the longitudinal direction. By supplying air to a bag upon one side and by discharging air from the bag upon the other side, the mat assembly is tilted.
