<p>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-apt 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 substantialy 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. The seat and back are mounted on the leg frame by two like supporting and connecting members at opposite sides of the chair, which also have provision for attaching an arm by a single screw or bolt or attaching a linking element for connecting chairs side by side in a row. The linking element is reversible so that it can be mounted with flat connecting lugs on the element directed either up or down. The arm comprises a base portion mounted at the side of the seat, two support arms extending up from the base portion in a V-configuration, and a molded plastic arm rest of open box shape pivotally mounted on the upper ends of the support arms to swing from a horizontal position for use to a vertical position for stacking, with a detent for releasably holding the arm rest in horizontal positon.</p> |
