A suspended shelf having hangers which support horizontal panels. The shelf hangers have a plurality of horizontal, vertically spaced crossbars each constructed of a U-shaped, downwardly opening channel member having a pair of side panels and a cross web connecting the panels extending between and longitudinally along the panels. A plurality of crossbeams, at least one near each end of each crossbar, extend between the panels and are spaced below the cross web. A plurality of manually removable sidebars extend between the adjacent vertically spaced ends of the crossbars. Each sidebar has a hook-shaped upper end for hanging over an upper one of the crossbeams and a lower, inwardly bent leg which extends along the underside of the cross web and above the crossbeam of a relatively lower crossbar to a downturned tip. Another pair of sidebars extend up from the uppermost crossbars and are fastened to the ceiling or other shelf support. A removable retaining means is inserted between each of the lower legs on the sidebar and its associated crossbeam for extending from the crossbeam to the leg for preventing significant movement of the leg and for interfering with the downturned tip to prevent withdrawal of the leg from the sidebar.
