Rack includes a left upright frame, a right upright frame, and a connector extending between and joining the left and right frames. The connector defines at least one passage extending along the left upright frame, for example, so that another rack may be nested within a volume defined by the rack for reducing storage space requirements. The rack may have its connector oriented so that the rack has a substantially Z-shaped frame, a substantially X-shaped frame, a substantially U-shaped frame, a substantially V-shaped frame, or a substantially H-shaped frame, for example, when viewed from above. A lifting element may be provided on an upper portion of the rack for use with institutional and industrial lifting mechanisms. The lifting element may be mounted on the rack so as to avoid interference with another rack when the racks are nesting.
