Tray members have a first pair of foot pads for engaging the support bracket feet and a second pair of footpads for engaging the upper end portion of the support bracket. The tray members and support brackets are interchangeable, with the latter supporting the former in a vertically spaced, stacked arrangement of two or more tray members.
