A pneumatic bed having an inflatable member, a fixed member, a valve, and an element having a port in which the valve is seated. This element normally confines inflation gas supplied to the inflatable member, and is normally movable with respect to the fixed member upon inflation of the inflatable member. A flexible member is also provided which extends between the fixed member and the valve, for unseating the valve when the element is moved beyond a predetermined point with respect to the fixed member, when the inflatable member is inflated beyond a predetermined limit.
