To adjust your Herman Miller Aeron for your height, use the paddle-shaped lever on the right side of the seat. Adjust the chair so your feet rest flat on the floor and your thighs are parallel to the ground, forming a 90-degree angle at the knees.
Step-by-Step Height Adjustment
To Raise the Chair: Lift your weight off the seat and pull the paddle lever upward. The chair will rise automatically using the pneumatic cylinder.
To Lower the Chair: Remain seated and pull the paddle lever upward. The chair will lower under your body weight.
The Ergonomic Target: Stop when your hips are slightly higher than your knees. If your desk is too high once your feet are flat, use a footrest instead of raising the chair and letting your legs dangle.
