How to Fix a Loose Armrest on an Aeron Chair: Replacing The Arm Index
If you're experiencing a loose armrest on your Aeron chair, don't worry—it's a fixable issue. This tutorial will guide you through the steps to replace the Arm Index, which will secure your armrest once again. Here's how to do it:
1. Gather Your Tools
Before starting, ensure you have the following tools:
A power drill or screwdriver with a Phillips head.
A wrench.
2. Remove the Armrest Screws
Begin by unscrewing the bottom two screws that hold the armrest. You can do this with either a power drill or a screwdriver equipped with a Phillips head. These screws are crucial for securing the armrest to the chair frame.
3. Loosen the Silver Bolts
Using your wrench, loosen the silver bolts that are now exposed after removing the armrest. These bolts are essential for holding the internal components together.
4. Remove the Broken Index and Metal Frame
Carefully remove the broken index and the metal frame surrounding it. The index is the part that needs replacement, and removing it will allow you to install the new one.
5. Install the New Arm Index
Take the new index and place it where the old one was. It's crucial to ensure the correct label is facing up—'R' for the right side and 'L' for the left side. This step ensures the armrest is correctly oriented.
6. Reattach the Metal Frame
Return the metal frame on top of the new index, aligning it with the silver bolts you previously loosened. This frame supports the structure of the armrest.
7. Secure the Plastic Piece
Press the plastic piece over the frame, making sure it aligns with the bolts. This plastic piece acts as a cover and helps secure the entire assembly.
8. Tighten the Bolts and Washers
Once everything is aligned, hand-tighten the bolts and washers. After hand-tightening, use your wrench to fully secure them. This ensures everything is tightly assembled and prevents future loosening.
9. Test the Armrest
Before proceeding further, test the armrest for tightness and proper function. It should feel secure and move appropriately without any wobble.
10. Replace the Armrest Cushion
Finally, place the armrest cushion back in its original position. Screw in the screws to tighten the cushion in place, securing it to the armrest structure.
Final Results
Once you've completed these steps, the regular function and setting of the armrest on your Aeron chair will be restored. This simple fix can greatly extend the life of your chair and ensure it provides the comfort and support Aeron chairs are known for.
