Abstract
An adjustable bed comprises a frame having a backrest arranged to be lifted by an actuator via a crank, and a thighrest similarly arranged to be lifted by an actuator. A legrest is freely pivoted to the thighrest. The angles of the parts are sensed and maintained in proportion by control means, so that as, for example, the backrest angle is steepened, the thighrest is also raised proportionately, but to less extent, taking the legrest with it.
