A tray may be temporarily attached to a supporting frame, such as a bed frame rail, to provide a support surface that enables the placement of various desired personal accessories in close proximity to persons enjoying limited mobility. A side support member is attached to an edge of the tray, and extends perpendicularly above and below the support surface of the tray. The upper portion of the side support is formed into a retaining hook, of a size permitting it to be received upon a circular bed support railing. The lower portion of the side support rests against a lower support railing. In this manner the lower side support resists the tendency of the retaining hook to rotate about the upper bed frame railing as accessories are placed upon the outwardly-extending support surface.
