  • Folding chair
    Patent number: 6406091
    Abstract: A folding chair includes collapsible rungs permitting folding in two directions. Stability is further enhanced by the upholstery which further forces the top rung of the chair downward making the chair rigid in the open position. Side rails and back supports slide freely along the chair's rear legs creating a folding mechanism that folds the seat upwards while also pulling the rear leg upwards in the same direction resulting in greater stability without increasing the height of the folded package.
