Fix Unresponsive Up And Down Control Lever Of Herman Miller Aeron Chair

You check out your new Herman Miller Aeron chair and immediately notice something odd, when trying to adjust the height of the seat, the up and down control lever simply won’t respond. 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. 
 

Please make sure that the cable is properly attached. See video below.

Please note: Make sure the lever’s cable is connected and secured at the correct location.
