A shelf and corner post combination wherein the shelf is adjustable into any of a variety of selected elevations. Each of the posts is preferably cylindrical and is provided with a series of vertically-spaced indentations along at least one side thereof. The shelf includes a perimetric frame having adjacent side frame members which merge to define a corner section having an inside contour corresponding with that of the post. Each corner section has at least one inwardly-projecting horizontal rib adapted to seat in any selected indentation of the post. Different means are disclosed for drawing the rib into a selected indentation and for locking the parts in interfitting relationship.
