Folding chair

Abstract

A chair has at least four support sections, including a locked lower leg, a free lower leg, a locked upper leg, and a free upper leg, where all four support sections extend from a hinge section. The locked upper and lower legs form a fixed locked leg angle, and the free upper and lower legs pivot between an open and closed position. A seat is secured to each of the locked upper leg and the free upper leg. In some embodiments, the bottom of a bag is connected to the locked lower leg, and one side of the bag is connected to the locked upper leg.
