ABSTRACT:
An adjustable bed is provided with two frames which rotate about the longitudinal axis of the bed. The rotation is facilitated by a plurality of motors mounted on an undercarriage in which the two frames nest. The motors are controlled by a control unit, which when actuated causes raising or lowering of the nested frames relative to the undercarriage. One or both frames may be raised or lowered at the same time. A limit switch is placed on the frames which prevents the angle formed by the two frames from becoming less than ninety degrees.
