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.

Abstract: In the illustrative embodiments of the invention disclosed, a portable, dual-height workbench has front and rear elongate vice members forming the work surface of the bench and a collapsible supporting structure which allows selective positioning of the work surface at either workbench height or sawhorse height above the floor. The collapsible supporting structure includes front and rear, flat leg frames pivoted at the upper ends thereof to the top structure of the bench and closed at the lower ends thereof by horizontal cross pieces. The leg frames pivot relative to the bench top structure between an erected position, in which the frames extend downward from the bench top structure in front-to-rear splayed relation, and a collapsed position, in which the leg frames extend generally parallel to the working surface of the bench.
