A tilting bed assembly is disclosed having a horizontal base frame and second frame hinged at one end to the base frame and an inflatable bag adjacent the other end to raise and lower one end of the tilting frame relative to the base frame. A hand-held three-position switch is connected through a relay to a three-position electrically operated solenoid valve and to an air compressor to selectively raise and lower the one end of the bed at the will of the person lying in the bed. The tilting frame is rigid to avoid articulation between its ends. Alternatively, instead of an inflatable bag, an electric actuator may be provided to raise and lower one end of the tilting frame relative to the base frame. A conventional foundation is received on the second frame with a stop on the second frame to prevent it sliding off when the frame is tilted.
