Abstract: A backpack unit comprising a frame of a material selected from a metal alloy, including, but not limited to, aluminum, aluminum alloy, steel, and steel alloy or plastic. The frame includes a U-shaped seat frame pivotally coupled at its ends to ends of a U-shaped back frame through a cross-member, a U-shaped front leg frame pivotally coupled to the seat panel and pivotally coupled at its ends to ends of a U-shaped back leg frame. The frame is capable of being folded such that the back frame, the seat frame, the front leg frame, and the back leg frame folds substantially parallel and adjacent to one another.
