Seat Height Button Knob Replacement for Herman Miller Aeron Classic Chairs by OfficeLogixShop
This product is designed and manufactured by OfficeLogixShop. It is not an OEM Herman Miller part. “Herman Miller” and “Aeron” are referenced solely to identify the compatible chair model. OfficeLogixShop is not affiliated with or endorsed by MillerKnoll, Inc.
Regain control of your seat height with this Seat Height Lever Replacement from OfficeLogixShop. If the control lever on your Herman Miller Classic Aeron is cracked, missing, or no longer engaging the mechanism, this part provides a direct fix. It replaces the external lever assembly to restore the original look and function of your chair.
Restore Function: The essential replacement part for broken or missing height control levers!
Why Replace the Lever?
The height adjustment lever is one of the most frequently used parts of the chair. Over time, it can wear out or snap off, leaving you unable to actuate the gas cylinder even if the internal cable is fine. This replacement part snaps into place to bridge the gap between your hand and the internal mechanism.
💡 Need the Cable too?
This listing is for the external lever only. If your internal cable mechanism is snapped or not engaging, you need our full Height Adjustment Cable Kit which includes the cable and this lever. Please check our other listings for the full repair kit.

Frequently Asked Questions
Is this the internal cable or just the lever?
This listing is for the external lever piece only. If your internal cable is snapped, you will need our full Height Adjustment Cable Kit.
Will this fit my Aeron chair?
Yes, it is designed to fit the Herman Miller Aeron Classic (Version 1). Please confirm your chair model before ordering to ensure a proper fit.
What if my chair is sinking?
If the lever is intact but the chair sinks, you likely need to replace the gas cylinder or adjust the set screw. Replacing the lever alone will not fix a sinking cylinder.
Do I need special tools to install this?
No special tools are generally required for the lever itself. It typically snaps or slides into position within the tilt housing.
