A storage unit for a refrigerator includes a flexible support made of nylon, wire, or any other similar flexible material. The storage unit includes a load support zone which varies in shape depending upon items placed thereon. Most preferably, at least the load support zone is constituted by a mesh which permits the flow of cooling air through the storage unit. The storage unit includes at least one attachment element for securing the flexible support directly to a refrigerator shelf and/or a liner of the refrigerator. The storage unit can be releasably attached or can be a permanent, but collapsible, fixture within the refrigerator.
