How To Ensure Your Herman Miller Aeron Chair Back Fits Perfectly?
Encountering issues with fitting the back of your Herman Miller Aeron chair can be puzzling, but it is often a simpler fix than it appears. Before assuming the back size is incorrect, follow our guide to ensure a perfect fit for your chair.
Tools Needed
- Aeron Back Replacement (If needed)
- Rubber mallet (optional)
- Diagonal bolt (provided with your chair)
Steps to Ensure a Perfect Fit
Verify the Back Size:
- Check the size of your Aeron chair back by feeling for Braille dots under the upper lip of the back. One dot signifies size A, two dots for size B, and three dots for size C. Confirming you have the correct size back is crucial.
Inspect the Yoke and Bushing Alignment:
- Look for any gaps between the metal yoke and the plastic bushing. A separation here is often the root of fitting issues.
Adjust the Yoke and Bushing:
- Manually: Try to push the yoke and bushing together with your hands. This is the most straightforward approach.
- Rubber Mallet: If manual adjustment does not work, gently use a rubber mallet to tap them closer.
- Diagonal Bolt Trick: For stubborn gaps, use a diagonal bolt approach. Start by inserting a back bolt into one corner and tighten it. Then, proceed to the opposite corner, aligning and inserting the bolt there. This method helps to realign the yoke and bushing by gradually tightening the bolts, which pulls the components together and closes the gap.
Finalize the Installation:
- After adjusting the first two bolts using the diagonal method, the remaining bolts should align more easily. Tighten all bolts to secure the back in place. This process not only closes any gaps but ensures the back is perfectly aligned and secured to the chair frame.
