Abstract
Foam plastic pads are contained in separate air-tight compartments with each of the compartments having an air passage which is controlled by a manually operated valve. The person using the cushion first allows air to enter the compartments, then rests on the cushion and allows the air to exhaust until the cushion feels comfortable as it forms to the contour of the person's body and the valve is then closed and the cushion will hold its shape for some time or until the valve is opened.
