Abstract
An armrest assembly includes an adjusting seat received in a base slideable in a length direction. The adjusting seat is slideable in a width direction relative to a seat fixed to the base. A first control button initially engaged with the adjusting seat can be operated to disengage from the adjusting seat and to disengage a transverse positioning block from the seat, allowing adjustment in the length and width directions. A lower rod is fixed to a chair body and is received in an upper rod movable in a height direction. A second control button is mounted in a window in the upper rod and includes engagement teeth engaged with a gear on a screw rod in threading connection with a screw rod coupling seat on the lower rod. The second control button can be operated to disengage the engagement teeth from the gear, allowing adjustment in the height direction.
