A chair includes a seat rotatably attached to a base with a pivot axle and coupled to the base with an actuator, to adjust the seat relative to the base. A seat back is rotatably attached to the seat and coupled to the seat with another actuator, to adjust the seat back relative to the seat. A foot support is rotatably attached to the seat and coupled to the seat with a further actuator, to adjust the foot support relative to the seat. The seat is adjustable relative to the base, the seat back is adjustable relative to the seat, and the foot support is adjustable relative to the seat with different actuators. The foot support may include a foot pedal slidably coupled to a plate with another actuator.
