ABSTRACT:
A shelving system having a first series of nestable shelving units and a second series of nestable shelving units. All units in the first series are nestable one within the other and all units in the second series are nestable one within the other. When both unitized series are fully nested, the second series nests within the first series in an orthogonal relationship. The sides of all units are designed so that a plurality of predetermined heights corresponding to the heights of different units can be achieved by the unitized shelving system when assembled.
