Abstract: A foldable chair includes a chair frame mechanism that is operable between an unfolded state and a folded state and that includes a seat unit, a backrest unit, and a support unit. The backrest unit extends from and cooperates with the seat unit to define a seating space when the chair frame mechanism is in the unfolded state. 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.
