Seat Pad Foam Insert Replacement for Herman Miller Classic Aeron Office Chair A B C Size Black/Gray (Black, C) MingYi.Office

I purchased a used Herman Miller Aeron C. It was in excellent shape for being 15 years old. If you have one, you know they are build to last. The only issue was the seat foam pad was missing. This replacement piece fit perfectly. I followed replacement instructions on other reviews and YouTube. Installation was a breeze. The double sided tape presented no issues. the protective strip peeled off easily. Just make sure you follow previous reveiws or YouTube advice and peel it back from one end while laying it down at the same time. I can see how peeling it all off and then trying to lay the pad down could be difficult as once the adhesive make contact with the seat, it's not coming off if you didn't get it straight. The pad fit as it should, is firm and restored the seat to like new condition. I would not hesitate to buy one again, but considering how it is made, I believe it will last for a very long time.

Excellent replacement. I own a size B chair, but the size C pad fit. It took some effort to jam it deep into the corners, but it was worth the effort. I tore the original pad when I tried removing it to clean my chair thoroughly. I was surprised that a new one would improve comfort, but it did. Money well spent if you are restoring your chair.

Bought this for my 20+ year old Aeron chair. It fits perfectly. I recommend loosening the front Torx screws that hold the mesh seat bottom insert to its frame. That makes removing the old foam cushion much easier than trying to pull it out with the mesh attached to the frame. It also allows for better vacuuming of the dust that collects there (you will be shocked at how much dust can collect there). It also allows you to scrape off the old adhesive that holds the original cushion to the plastic frame. At that point, installing the new foam cushion (it has double-sided tape to stay in place) to the chair and re-installing the seat mesh over it is a snap. Works great. I definitely feel more thigh support when sitting now.

This seat foam pad didnt work in my application. The tape didnt seperate from the glue on the pad correctly and no glue was left on the foam pad. There was no way for me stick it or glue it like i needed to on my herman miller aeron chair.

Got this to replace a worn out pad on my Aeron Classic Size C. Installation was easy. Fit like a glove. Provides just as much support as the OEM pad, if not more. Very comfortable.

Good replacement for the original pad, fits well. Makes a difference in chair comfort. The chair itself has guides for placing the pad. 1 star off for near-impossibility of removing the adhesive tape cover.

Perfect replacement for foam pad on Aeron size C. Exact right size and thickness. Also, the adhesive tape backing was easy enough to remove, unlike some other reports here. I highly recommend removing the mesh seat before attempting to replace the foam pad. Just turn the chair over (on carpet preferably), and remove the ring of screws around the perimeter of the seat. Turn the chair back upright, and pull the mesh panel out, using your fingers to pry out the plastic ring holding it to the chair. This gives easy access to the pad, and enables a perfect fit. Repeat the steps in reverse to reassemble the chair. Good as new!

Leaving this review for different products. Not really knowing which to buy of two size-C-specific pads, I bought one that was $12 and the other was $19, give or take. Here you see some photos of the two the $12 one is about the same dimensions may be a little bit bigger in the horizontal plane than the $19 one. The $19 is probably ever slightly closer to the original cut-out size on an Aeron Classic’s pad while the $12 is closer to the original in thickness. The original might be a little denser but that may not be a fair comparison if these compress with use. Additionally, the $12 one is just a little bit thicker. They both have the same amount of resistance/compressibility, so I went with the $12 one. Both products seem fine. You have to remove the mesh to install. You can’t possibly hope to shove a sticky pad into a narrow slot and hope for a good result. And then you have to do some ginger convincing when re-screwing the mesh. Some of these may not work great on an Aeron remastered.
