Important Compatibility Notice for Classic Aeron Mechanism Covers

There are three versions of the Classic Aeron mechanism covers:

• First Generation: 1994 to 1999
• Second Generation: 2000 to 2005
• Third Generation: 2006 to 2016

We currently only sell the third-generation cover set.

If your Aeron chair is from before 2006 (first or second generation), we strongly recommend purchasing the full set (both top and bottom covers) to ensure compatibility.

If you are buying only the top or bottom cover, you must verify that it matches your existing part. Compatibility is not guaranteed unless the teeth and shape match exactly. Please check your current cover’s design carefully before purchasing a single replacement.

When you purchase the full third-generation kit, both parts are compatible with each other regardless of your chair's generation.
