A beach chair is made of three tubes, the tubes being bent three-dimensionally, and a method renders the forming economical. The three tubes are bent into the same shape, including parallel legs and a bend connecting the legs. The bend is also curved out of the plane of the parallel legs. The seat has a sling between two legs, and the bend turns down to act as a rear support; the back extends up from the seat; and, a support connects the seat and back for rigidity, and the bend turns down to act as a front support. An optional leg rest is the same shape again, having its legs attached to the seat, and its bend turning down to support the leg rest. To bend the tubing, a thermoplastic trough is shaped as desired, and a heated tube is conformed to the trough.
