Abstract
A foldable chair is provided. The foldable chair includes two supporting side frames, two connecting plates, a seat plate and a back plate. The two supporting side frames are each formed with a first supporting part and a second supporting part. The two connecting plates are arranged between the two supporting side frames and are pivotally connected to the two supporting side frames. The seat plate is arranged between the first supporting parts of the two supporting side frames, and both sides of the seat plate are pivotally connected to the first supporting parts of the two supporting side frames. An inner side of at least one of the two supporting side frames, the two connecting plates, the seat plate, or the back plate is formed with a reinforcement structure.
