Abstract
An inflatable cushion is disclosed, having features that allow deflation of the cushion to be controlled. The cushion includes an inflatable bladder having a support therein and a valved exhaust tube in fluid communication therewith. An indicator coupled to the exhaust tube indicates when fluid is exiting the exhaust tube. When sat upon, the cushion deflates only by a preselected amount. This allows the cushion to be consistently and easily deflated to a predetermined inflation height.
