ABSTRACT:
A tiered desktop tray assembly including a lower tray and an upper tray utilizes a pair of spacer brackets operatively connected between the trays for supporting the upper tray and the lower tray. The spacer brackets are maintained in a stressed condition while interconnected between the upper and lower trays so that the interconnected relationship of the brackets and trays is enhanced by the stress under which the spacer brackets is maintained.
