A merchandise display apparatus is disclosed, which comprises a foldable/erectable tubular structure formed of a series of foldably connected wall panels. When erected, the tubular support has at least three sides, at least one of which has an intermediate hinge line to accommodate a bellows fold. A plurality of caster assemblies is provided, one for each corner of the polygonal configuration formed by the erected tubular support. The caster assemblies include rigid channel-forming flanges, arranged at a predetermined angle corresponding to the corner angles of the erected polygon. When the foldable polygon is erected, the caster assemblies are applied over the lower end portions, at each corner, providing mobile support for the structure and simultaneously rigidly securing the otherwise foldable wall panels in the desired, erected cross sectional configuration. A rigid forming panel is inserted into the erected structure and is supported by the caster assemblies. A cross brace, formed by intersecting flat panels, is positioned within the polygon, extending between corners to impart strength and rigidity to the structure. One or more product trays are supported on the panels of the cross brace.
