Abstract: A metal patio chair has a seat frame made by the steps of providing a pair of seat rails in the form of elongated metal tubes, placing a mandrel inside each tube to reinforce the wall of the tube, punching a series of spaced apart holes in the wall of the tube while the mandrel contained in the tube holds the shape of the tube while punching out the holes, removing the mandrel, providing a plurality of metal slats having a cross-sectional shape to match the shape of the holes punched in the seat rail tubes, inserting ends of the metal slats in corresponding pairs of holes formed in the tubes to form a ladder type chair frame in which opposite ends of the slats are held captive in corresponding holes in the tubes, and are rigidly securing the slats to the seat rail tubes to lock the slats in palce in the tubes to provide a rigid seat frame structure elevated above the ground by a supporting sub-structure to which the finished seat frame is attached.

Abstract: A spring-action chair comprising a seat frame having left and right sides and left and right spring-action support means rigidly secured to the left and right sides of the seat frame for elevating the seat frame above the ground. Each support means comprises an elongated, continuous support member of composite configuration having sections which include a first section extending upwardly and rearwardly from a first ground engaging end along a first angle, the member then having a first reversed bend in an elevated horizontal intermediate section extending forwardly therefrom, adjacent the seat frame to a second reversed bend, with the member then having a second angular section extending downwardly and rearwardly at a second angle and terminating at a second ground engaging end.
