An adjustable bed comprising a chassis, a bed frame tiltable relative to the chassis, at least one linear actuator disposed on the chassis at each end of the bed, and means articulatedly connecting the linear actuators to the bed frame so that the bed frame may be moved to various elevated and longitudinally tilted positions, which means comprises an intermediate frame connected to the bed frame and the chassis, differential units connecting the intermediate frame to the linear actuators, said differential units being rigidly interconnected whereby the bed frame and intermediate frame are arranged to pivot about a longitudinal axis relative to the chassis, means arranged at the bed foot for ambilateral pivoting displacement of the bed frame and intermediate frame about the longitudinal axis, a split leg rest on the bed frame, a supportable back rest articulated in cantilever fashion in said bed frame, means for manipulating the back and leg rests, and at least one securing rail provided on said bed frame and adapted to support auxiliary appliances.
