Abstract: An adjustable shelving rack is disclosed having two elements. The first element includes two sections interconnected by a series of planar rungs, one of the sections being disposed above the plane formed by said rungs and the other section being disposed below the plane formed by said rungs. The second element includes two sections supporting a series of planar rungs having both of its sections disposed on the same side of the plane formed by said rungs. The rungs of both elements lie in the same plane when the two elements are coupled together.
