Sit down in the chair. Place your arms on the armrests on both sides of the chair. Adjust the armrests' height by pressing the button on the outside of the armrests. While holding the button, move the rests up or down, as desired.
Adjust the seat's height. Pull the paddle, located on the rod that protrudes from the right side of the chair, to increase the height. Sit on the chair while holding the paddle to lower the chair. Release the paddle when you have achieved the desired height.
Adjust the seat slider and back angle. Sit on the chair and then pull the rod out to the "unlock" position. Lean back and slide the seat forward, or back. Push the rod back into the "lock" position when you have reached the desired position.
