Fix Herman Miller Aeron Chair Going Up And Down On Its Own

You check out your new Herman Miller Aeron chair and immediately notice something odd, the chair moves up or down or both on its own. Luckily, there is a simple one time fix for this issue. Simply, pop open the cover of the Aeron chair controls under the seat. You will see a screw sitting on top of the chair’s cylinder. Tighten or loosen the screw just a bit. That is it, your Aeron is now fixed. You can watch the following video to see how easily your Aeron could be fixed.

Please note: Do not overtighten the screw or loosen the screw too much because the chair will go up and down on its own. Please see the photos for correct position of the screw.
