This kiosk display unit comprises a pedestal consisting of three identical sheet metal panels which are secured together, to form a structure closed upon itself, by interengaging hook tabs and tab-receiving openings in flanges along edges of the panels. Because the panels are identical, to engage second and third panels to opposite edges of a first panel, the second panel must be moved relative to the first panel in one direction and the third panel must be moved relative to the first panel in the opposite direction. To engage the second and third panels with each other, a twisting movement is imparted to the assembly to allow the hook tabs and openings of the second and third tabs to become engaged with each other. Trapezoidal tabs and openings are used to facilitate entry of the tabs into the openings when the structure is twisted. The display unit also comprises a closed display section comprising three panels and three posts. Each post receives edges of two panels and retains the panels by the engagement of the outside face of each panel with a retaining flange of the post and by the engagement of a tongue of the post with a groove, on the inside face of each panel, extending parallel to the panel edges and spaced therefrom by a short distance.
