Abstract: A tray assembly may be used in combination with inclined, stepped, level or variable level support surfacing. The tray assembly may be used in tandem with identical embodiments of the tray assembly for forming larger, linked tray assemblages. The tray assembly may comprise a plurality of legs, which are stowable in a primary tray structure when not being used to elevate the tray structure above a support surface. When used to elevate the primary tray structure above variable level support surfacing, the legs may each be adjusted relative to the primary tray structure for properly maintaining a horizontal tray configuration relative to the support surfacing. The tray support legs are removably receivable in the tray-receiving slots for stowage, and are removably receivable in leg-receiving apertures for supporting the primary tray structure in horizontal spaced relation relative to a support surface.
