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.
