The drawer outer wall has an outwardly projecting shelf and a lip extending above the shelf. A cover disposed over the housing has an endwall which covers the lip for retaining the drawer in the housing. Preferably, the shelf extends around the perimeter of the housing for supporting bottom edge of one or more of the walls of the cover. The tool box cover is sturdy enough to be used as a stool.
