A mobile positioning, supporting and transporting system has two upright generally circular, oblong, elliptical or polygonal support structures joined together with lateral support members to form a freestanding structure with a roughly circular geometry so that it may be tipped end-over-end or rolled to translate from place to place. Any objects attached to or suspended from the structure within the volume space between the support structures readily are moved to a different location or position as desired. Alternatively, the support structures are disassembled and segments thereof may be aligned adjacent one another to form a cargo bin or cart to hold remaining portions of the structure and accessories for storage or transport.
