ABSTRACT:
A convertible utility chair includes a frame structure comprising a number of frame elements of preselected shapes for providing, when folded, a compact, transportable carry-all including ample open volume for storage purposes. Frame elements are joined to one another by rivets and subassemblies that allow the conversion from chair to carry-all configuration by a simple application of manual pressure.
