How do I adjust a Herman Miller Aeron?

The way to adjust a Herman Miller Aeron chair depends on which part you wish to reposition. To raise or lower the seat, use the paddle-shaped lever found on the right side of the chair. Reach for the lever on the left side to tilt the seat. A lever on the base of the arms controls the arm height, and you can modify the arm angle by pivoting the arm pad.
