Upper and lower shelves are supported on a rotatable post in a cabinet to turn outwardly about the axis of the post from a stored position to an accessible position, the lower shelf being turned out automatically when the door of the cabinet is opened. The lower shelf is mounted to turn relative to the post while the upper shelf is mounted to turn with the post so as to enable the lower shelf to turn outwardly independently of the upper shelf and to enable the use of a simple lower bearing element for rotatably supporting both the post and the lower shelf.
