Abstract: The invention relates to a cot comprising four height-adjustable side parts (3). In order to enable the side parts to be vertically adjusted without applying a force, a plurality of controllable motors (4) is provided on the bed (1) for lowering and raising each side part (3), such that the height can be continuously adjusted. An electric motor or a hydraulic motor is used as the motor (4), and a vertical hollow post (5) is provided on at least one of the corners of the bed (1), the motor (4) being arranged in the cavity (10) of said post with a spindle-nut drive. The hollow post (5) is embodied as an extruded profiled element (38) with different functional moulded elements.
