FOAMON Seat Foam Insert Replacement - Compatible with Herman Miller Classic and Remastered Aeron Size C Large - Thick, High Density Pads - Cushion with Cleaning Wipes and Adhesive - Easy to Install

Bought to replace the padding for a classic Aeron size C that I got 2nd hand. Didn't think to replace the existing padding until 2.5 years after I've had the chair.It was hard to reach under the chair to remove the old foam due to the location of it on the chair and the glue holding it down. I kept grabbing at foam until most of it was out, gave it a quick wipe, and then applied the FOAMON cushion. The cushion has one double sided tape and it's a tight fit. It didn't feel right when I sat on it the first time, but after a month it is much nicer than the old, flattened one.

Fits just right, feels great.

I have a refurbished chair and never realized the foam is missing. This piece is a perfect replacement.

Exact replacement of original.I recommend removing the seat mesh first though. This can be done easily by unscrewing all the Phillips head screws under the seat.Now my chair is fully renewed and clean :)!

Great product which fits as expected. Have to be careful during install because it can rip easily.

The large size fit great on my size C chair. Could have bought the smaller size but I like it better now since it covers the entire width on my seat.

Perfect fit for my "C" size Aeron. My old one was almost completely gone - this was easy to install. I had no issue with the feel of the new foam - very comfy.

The seat foam works well with me chair, and it has a great quality and support. It seems my chair does not come with a foam, but it improves the comfort. I've ordered a second just for backup.
