Herman Miller Replacement Classic Aeron Office Chair Seat Foam, Fits Medium Size B and Small Size A

The original seat pad was ‘toast’. The replacement pad breaths life into my Aeron chair for many more years of service!

Have an Aeron chair, used for ~20 years, still great but noticed the foam padding in front of chair seat was basically gone. Bought this as replacement, super easy to swap in and now this great chair even more comftorable.

Works well for the Herman Miller Aeron chair.

Works really well as a replacement cushion. It's easy to install; removing the native cushion was most of the work. I recommend watching a video tutorial to clear up any doubts.

Pad is a little bigger than what I believe the original to be, but works fine. I wouldn’t recommend removing the seat pan. Tried that first and the screws wouldn’t catch.

OEM item to replace the one that was disintegrating on my Aeron. After about 15 years, it was time to replace.

Does what it needs to do, holds up well.

Perfect fit! The previous pad was so degraded there wasn’t much to remove. I definitely notice an improvement, should have replaced it a long time ago.

Feels good and comes with 3M adhesive. Instead of pulling out the old piece under the sitting mesh, I remove the mesh instead and cleaned it as well. Putting the mesh back was a little challenging. Need to stretch it a bit for the mesh to stay taut. Good thing the design is very well thought out and there is a groove to fit the mesh back in.
