ABSTRACT:
The present invention is a shelving system having height adjustable shelves. The shelving system includes a plurality of elongated support posts having recesses spaced along the longitudinal axis. At least one resilient support post clip is attached to each support post within a recess to provide a shelf support. A shelf member having recesses at least partially accepting the post clip, is positioned in detachable nesting relationship with the support clips.
The shelf member further includes an upper surface having alternating transverse ribs and recesses, and a lower surface having alternating longitudinal ribs and recesses. The ribs serve to reinforce the shelf member both longitudinally and transversely.
Each shelf member further comprises an outward projecting support rail extending along one or more edges of each shelf member. A connecting mechanism simultaneously engages the support rails of adjacent shelf members and retains the adjacent shelf members in fixed relation with each other.
