Abstract: A display assembly includes a box of articles to be displayed at a point of purchase. A bottom portion of the box is glued to a tray unit glued to the top deck of a display base. The tray has side and front flaps providing a receptacle for the bottom of a shipping sleeve surrounding the box, with the flaps taped to the shipping sleeve during shipment. Parallel, horizontally-spaced runners support the display base above the floor. A roller mounted between the runners near the rear ends thereof enables tilting the assembly onto the roller to conveniently roll it along the floor from one location to another, when desired. The entire display base, including the deck, runners and roller assembly, is made of fibreboard. The runners, bearing boxes and cross-bracing are made of die cut corrugated fibreboard build-ups. The roller assembly is made of a combination of spiral wound paper tubes, the inner tube being the axle received in die cut sockets in the bearing boxes.
