Provided is a folding chair, comprising two front foot tubes, two back foot tubes and a seat cushion plate, wherein one of the front foot tubes is arranged to intersect with one of the back foot tubes; and further comprising two washers, wherein one of the washers is arranged at an intersection of one of the front foot tubes, i.e. the washer being located between the front foot tube and one of the back foot tubes, with one pin successively passing through the front foot tube, the washer and the back foot tube. Each of the washers is provided with a curved base and a support bowl, wherein the support bowl is located at a central area of the curved base, with the centre of the support bowl being provided with a through hole; and the curved base is fixedly connected to the front foot tube. The beneficial effects of the present invention are provided as follows: the washer arranged at the front foot tube is provided with the curved base and the support bowl, the curved base matches a surface of the foot tube in terms of shape and can be firmly connected to the foot tube, and the front foot tube and the back foot tube are spaced apart by the support bowl, such that the structure can reduce the friction between two foot tubes, so as to prevent a hand from being clamped between same, and can improve the load bearing thereof and at the same time reduce the weight of the folding chair. The folding chair of the present utility model can increase the intensity of an impact test in an obvious way.
