Aeron Chair Repair: How to Restore Your Herman Miller Chair

 The Aeron chair by Herman Miller is renowned for its ergonomic design, durability, and comfort. However, even the best office chairs require maintenance and repairs over time. Whether your Aeron chair has a broken tilt mechanism, worn-out seat mesh, faulty armrests, or sinking gas cylinder, repairing it can extend its lifespan and save you from purchasing a new one. In this article, we will discuss common aeron chair repair issues, solutions, and where to find replacement parts.

Common Problems with Aeron Chairs

Despite being built with high-quality materials, the aeron chair repair can develop issues after years of use. Some of the most common problems include:

1. Tilt Mechanism Malfunction – The chair may not recline properly, or the tilt function may become stiff or unresponsive.
2. Sagging or Torn Mesh – The Pellicle mesh, known for its breathability, may sag or tear, reducing comfort and support.
3. Loose or Broken Armrests – The armrests may become loose, stuck, or cracked, making adjustments difficult.
4. Worn-Out Casters – The chair wheels may stop rolling smoothly, making movement difficult.
5. Gas Cylinder Failure – If the chair sinks or does not hold height adjustments, the gas lift cylinder likely needs replacement.

How to Repair an Aeron Chair

1. Fixing the Tilt Mechanism

If the tilt function is stiff or unresponsive, try adjusting the tension knob located under the seat. If that does not fix the issue, the tilt mechanism may need replacement. This involves removing the chair’s base and installing a new tilt assembly, which can be ordered from Herman Miller or third-party suppliers.

2. Replacing the Seat Mesh

A sagging or torn Pellicle mesh reduces comfort and support. While replacing the mesh requires disassembling the chair’s frame, it is a cost-effective way to restore its original comfort. A replacement seat mesh can be purchased online, and professional repair services are available if DIY installation is too complex.

3. Repairing or Replacing the Armrests

If the armrests are loose or damaged, they can often be fixed by tightening the screws underneath. If the armrests are cracked or completely broken, replacing them with new ones is the best solution. Most armrest replacements are easy to install using basic tools.

4. Replacing Chair Casters

If your Aeron chair wheels are not rolling smoothly, replacing them is simple:

• Turn the chair upside down.
• Pull out the old casters or use a screwdriver for leverage.
• Insert new casters by pushing them firmly into place.

5. Replacing the Gas Cylinder

If your Aeron chair sinks, the gas cylinder is faulty and needs replacement. To replace it:

• Remove the chair base by unscrewing the cylinder.
• Insert the new gas lift and reattach the base.
• Test the height adjustment to ensure proper functionality.
