ABSTRACT:
Adjustable step stool for exercise purposes includes an inverted cup-shaped top section and a generally annular bottom section. The bottom section is provided with a series of vertical posts or ribs integrally molded therewith along its interior wall, these ribs having support ledges on both their tops and bottoms for alternatively supporting the bottom edge of the top section at different heights. When the top section is used alone, a lowest height step is provided. When the top section is supported in the bottom section in a first attitude of the bottom section, a step of intermediate height is provided. And when the bottom section is flapped over and the top section is supported in the bottom section in this inverted position, a step stool of third and greatest height is provided.
