    Abstract: A mobile three-shelf table wherein the bottom, central and top shelves are interconnected by readily assembleable corner legs fitted to cooperating connecting portions on the shelves. The table includes wall panels partially enclosing the space between the bottom and central shelves which are mounted in the table with effectively minimum fastening structures. The panels define a front access opening. A door is hingedly mounted to one of the side panels for selectively closing the access opening. The shelves and panels define cooperating interlock structures for effectively retaining the panels in assembled relationship in the table. Straps are provided for reinforcing the mounting of the side panels to the front corner legs to provide improved strength and rigidity at the front access opening. In the illustrated embodiment, the space between the central and top shelves is open.
