ABSTRACT:
An improved structure for a seat supporting frame of a chair includes a seat, front legs and back legs mounted on the two sides, a horizontal support having flattened ends and forming a bent section. The bent section is welded with the inner side of the front leg. The two ends of the bent corners are formed with a curved section. The sides of the seat has vertical support pieces, one end of which is set on the side of the seating frame, and the other end is connected to the front leg. A stop abutment, mounted on the lower section of the vertical support piece, is firmly abutted to the inner side of the curved section of the horizontal support, so as to prevent it from sliding and fracture. The horizontal support, the front leg, the vertical support piece, and the stop abutment are held together tightly.
