摘要： A multifunctional grandstand chair includes a chair frame, a cushion movably arranged on the chair frame, and backrest cloth. The chair frame includes a base frame, a backrest tube and two foot supports, which are respectively pivoted to two sides of the base frame and capable of being inwards folded onto the base frame or outwards unfolded to support the base frame. The multifunctional grandstand chair further includes fixed connecting pieces connected between the base frame and the foot supports to limit the maximum unfolding angle of the foot supports. When the multifunctional grandstand chair needs to be transformed into a grandstand chair structure, the foot supports are folded onto the base frame. When the multifunctional grandstand chair needs to be transformed into a common chair, the foot supports are unfolded to be supported on the ground.

摘要： The invention discloses a double folding chair with rotation angles. The double folding chair comprises four backrest pipes and two armrest pipes, wherein the a wrest pipes and the backrest pipes form a folding chair frame, rotation-angle transverse-bracing pipes are arranged between the two backrest pipes in the middle so that a flare angle can be formed between two chair backs, and intermediate connecting pieces which can rotate coaxially are arranged on a front support of the folding chair frame so as to be matched with the rotation-angle transverse-bracing pipes. Since the flare angle can be formed between two chair bodies, chair users can communicate conveniently, and the double folding chair has the advantages of being reasonable in structure, good in user experience etc.
