Arm Index Replacement Kit 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.
Restore the precise pivoting action of your armrests with the OfficeLogixShop Aeron Arm Index Kit. If your armrests are loose, refusing to lock into angle, or wobbling excessively, the internal indexing mechanism is likely worn out. This upgraded kit not only restores the factory-fresh click and lock feel but is also engineered to fit all versions of the Aeron Classic arm.
Universal Fix: The only kit designed to repair both Thumbwheel and Flip-Lock arm styles!
Why Replace Your Arm Index?
The "index" is the internal component that allows your armpad to pivot left, right, or center and lock into place. When it breaks, the armpad spins freely or feels unstable. Our replacement part fixes this issue and is specifically optimized to reduce the inherent wobble found in older arm designs.
Key Features
| Feature | Benefit |
|---|---|
| Universal Compatibility | Fits both the older "Thumbwheel" (wheel adjustment) and newer "Flip Knob" (lever adjustment) Classic arms. |
| Wobble Reduction | Engineered to fit tighter than the original, significantly reducing armpad play on older models. |
| Durable Construction | Made from high-strength industrial plastic to withstand daily adjustments and pressure. |
| Complete Repair | Contains the specific indexing block needed to restore the 3-position lateral locking function. |
What Is Included
This listing is for two (2) kits, which repair two armrests.
Compatibility
