ABSTRACT:
A pneumatically adjustable bed in which a series of air bladders are strategically placed to adjust the posture of the mattress on a bed so that the occupant of the bed can adjust his posture without having to move. A centrally disposed pneumatic manifold with a motor and a blower is employed to inflate and deflate the various bladders separately, thus posture can be very precisely controlled.
