ABSTRACT:
Tubular assemblies are interpivotally connected so as to form a stable seat when the assemblies are pivoted into an expanded position but form a wheeled carryall when in the collapsed position. One assembly cooperates with the other assemblies to provide a seat back when in the expanded position and likewise provides a gripping handle for manual movement when the assemblies are in the collapsed position. A second of the assemblies has wheels attached thereto which are pivoted out of engagement with the surface when in the expanded position but pivoted so as to provide wheeled engagement with the surface when the assemblies are interpivotally collapsed. The third assembly cooperates with the wheeled assembly to provide the seating arrangement in the expanded configuration and the carryall portion when in the collapsed configuration.
