A folding super chair includes a front leg frame, a backrest, a backrest frame and a ganging device. The backrest frame has a contour corresponding to an upper inner portion of the front leg frame and an L-shaped cross section. The backrest frame is disposed between the front leg frame and the backrest. The backrest is placed on the backrest frame, which relieve stress. Thus, a ridge of the backrest does not deform, and the backrest is securely fixed on the folding super chair. The ganging device includes a main member, a slot fastener and a knob fastener. The main member has a front face, a rear face and two side faces. The rear face is larger than the front face, and therefore the two side faces form an included angle therebetween. When the folding super chairs are lined up and connected by the ganging device, the folding super chairs form a curved row.
