A rotary shelf assembly having shelves mounted on a vertical post is connected to a cabinet frame by upper and lower mounting brackets interacting with bearing members to support the post. The assembly is adapted to be mounted in the corner of the cabinet frame. To adjust the vertical position of the cabinet frame, the lower bearing element is adjustable by means of a threaded shaft which raises and lowers the vertical post. The threaded shaft is raised and lowered by means of either a knurled cylindrical element or a toothed cylindrical element, accessible through the post by rectangular openings. By rotating the toothed or knurled elements, the shaft of the vertical adjustment means rotates within the mounting bracket, thereby adjusting the height of the rotary shelf assembly.
