The support unit is mounted to the backrest unit, and includes a spine rod disposed rearwardly of the backrest unit and being upwardly and downwardly movable for driving operation of the chair frame mechanism between the folded state and the unfolded state. A movable seat is sleeved on and slidable along the spine rod. A cushion pad is connected to the movable seat and is disposed between the movable seat and the backrest unit.
