Abstract

A combination folding seat and backpack comprises first and second frame members which are pivotally connected together and may be arranged so that the frame members are connected by a seat panel. Back straps are attached to the frame members and a bag enclosure including cushioning material is also incorporated and mounted on the frame members so that the construction, when in the backpack configuration, enables utilization of one of the bag enclosure as a lumbar support.
