The intermediate tray has an adjustable positioning assembly and is in releasably slideable engagement with the vertical support members. The top tray includes molded utensil clips and has a handle with an integral trash bag retention portion. The upper tray also has upper support member engaging portions. The vertical structural support members includes at least one hollow rod structural member which is engaged and secured in compression between upper and lower support post engagement portions. The adjustable positioning assembly includes releasable clamping systems for releasably clamping the intermediate tray in variable vertical positions between the base and the top tray. In an alternate embodiment, an adjustable positioning assembly is also provided which includes a bore and counterbore which define a shoulder arrangement in the intermediate tray.

The counterbore engages the ring to hold it in position in the groove while the shoulder rests on the ring to support the tray at a predetermined position.
