ABSTRACT:
A shelving assembly comprises two side pieces, a back plate positioned between the side pieces, a plurality of adjustable shelves, and a plurality of edge strip members. The latter connect rear edge portions of the side pieces to vertical side edges of the back plate. Each edge strip member is securely attached to the back plate and is positioned along the side edges of the back plate. Each edge strip member includes a forwardly directed channel which slidingly engages around at least a part of an associated vertical rear edge of a side piece in a manner binding the side piece to the side edge of the back plate independently of separable fasteners.
