ABSTRACT:
In the illustrative embodiments disclosed, a novel step stool structure includes the sitting and climbing features of a traditional step stool and, in addition, a vise unit affording a vise action and a working surface for carpentry or other tasks. The vise unit comprises a pair of relatively movable vise beams, the upper surfaces of which provide the working surface. One or more movable seat-forming members, by themselves or in conjunction with the vise beams, provide a seat for use of the stool in the traditional step stool sense. Movement of the movable member or members allows conversion of the stool from a seat mode of use to a workbench mode of use and vice versa.
