A rotating stacked tray apparatus is disclosed which comprises a base, a lower tray which rotates on the base which accepts a shaft coaxially mounted on the lower tray, which such shaft is used to support one or more upper trays or shelves. The upper trays have central openings which fit around the central shaft. The upper shelves are supported by horizontal support slits in the central shaft and matching extending portion of each shelf. The apparatus in its preferred embodiment, is designed to be packaged unassembled in a flat package and to be assembled without tools.

A rotating stacked tray apparatus comprising; a base; a generally circular lower tray rotatably mounted on said base for rotating around its axis; a shaft coaxially mounted on said lower tray which comprises a generally rectangular flexible element, having a series of connected arc portions wherein the arc portions are generally inflexible and the arc connections are flexible, such that the shaft formed thereby has an undulating arc surface, and having connection means on opposing edges, such that said shaft is formed when said opposing edges are brought together and connected; and at least one generally circular shelf having a central opening for receiving said shaft and supported along the height of said shaft, wherein the central opening of said at least one shelf has complementary shape with said shaft, such that said opening is a series of arcs meeting at apexes around said opening, wherein said at least one shelf is supported by said shaft by means comprising horizontal slits centered on each of the arc portions of said shaft in the same plane, said slits having generally the same width as said shelf, and the length of said slits being such that the apexes of the opening of said shelf may be securely received within said slits when said shelf is rotated around the axis of said shaft in the plane of said slits.
