ABSTRACT:
A device particularly useful for comfortably supporting a person includes a hollow member having upper and lower walls joined to each other around their periphery and adapted to be air pressurized. The upper wall is formed with a plurality of openings at spaced locations receiving a plurality of valve members, one for each opening. Each valve member is normally biassed to a closed position with respect to its opening, but is engageable by a person supported by the hollow member and is moved thereby to an open position to outlet air from its respective opening.
