  • Patent number: 5002337
    Abstract: A stackable chair has a leg frame on which a seat and back are mounted. The leg frame comprises two lengths of flat tubing of dumb-bell shaped cross section bent to provide contiguous parallel portions which extend centrally transversely of the seat, portions extending from the ends of the parallel portions toward corner regions of the seat and portions bent downwardly to form the legs which are substantially in a vertical fore-and-aft plane but incline forwardly and rearwardly. When the chairs are stacked the legs of dumb-bell cross section nest with one another. The seat has a width substantially equal to the overall width of the leg frame and has cut-out corner regions to accommodate legs of superposed chairs when stacked. Plastic gliders at the bottom of the legs have support portions extending up along the legs for supporting superposed stacked chairs.
