The sick-bed is comprised of a bedstead and a bed frame as the mattress support, mounted cardanically on same for the decubitus prophylaxis, which bed frame can be precessed by means of a drive unit. The bed frame is cardanically suspended on at least three, in particular four lifting drives, which are separate from each other and continuously height-adjustable. Said lifting drives are controllable in such a manner that the central normal of the bed frame running through the gravity center of the bed frame is allowed to carry out a continuous, damped and slow precession movement.
