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

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.

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.

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.

I was gifted a Herman Miller Classic and before putting it to use I grabbed a few items from around Amazon to freshen it up. I thought I might have to replace the seat, but I thought I would try this first. I got it and when I opened it and compared it to the one in there, it looked way too small. However, looking into it a bit further, it was not. The material is designed to kind of smush out and fill the space. Once I installed it and sat in it for a few days it started to mold its way it into the seat and filled it. Seat feels brand new and supportive again. 8 hour workdays followed by gaming ain't no thing.

I purchased for my remastered edition based on a review here. While it wasn't super problematic, I felt that occasionally my legs rest on the frame of the seat pan which is somewhat uncomfortable for a long period of time. After doing some research and sleuthing, I found that the design from the classic to the remastered is mostly the same, but only a 1% increase in forward tilt in the chair to reduce pressure in the seat pan edge. However, it seems that there is a net benefit to the cushion regardless of the minor changes on the remastered edition. This pad lined up and fit nicely, though I have no understanding of how it compares to stock. It sits a bit high at first, but it is super soft foam which flattened to the curve of the pan very quickly. Would recommend for those interested in marginally improving comfort on an already great chair at a very low price point.

Have probably bought 20+ of these. Great replacement for deteriorating foam on your Aeron seat.

Having short legs and being overweight It has always been difficult to find a comfortable work chair. The Herman Miller Aeron Chair,C is well constructed and is adjustable enough that I can put my feet flat on the floor and have a seat large enough for my derriere. However because of the hard edge at the front of the seat I was experiencing pressure on my legs, enough pressure to become uncomfortable with in an hour. This is one of the newer Aeron models not the original; therefore the cushion was not included with the chair. Thinking that this cushion would help a purchased this cushion. The cushion installed easily, and it performed as described in the advertising. The result was that it moved the pressure point an inch or so up the back of my leg and made the edge a bit broader; but did not solve my issue. I removed this cushion, and I purchase some DIY (do it yourself) chair cushion foam, Two inches of HD50 foam and two inches of HD36 foam. Cut the foam myself to fit the chair. with 4 inches of foam I was still able to put my feet flat on the floor. This has helped, but my feet and legs still start to feel uncomfortable after an hour and a half or so. $70 for the DYI foam, cheaper than a new chair.

The foam pad replacement sold for the C size chair is okay, it raises up more than the old pad, so I feel it more on the back of my legs when sitting. Its length is just about 1 inch too short on one side to fit all the way across as snug as one would like too. Overall not a bad buy for a replacement pad when yours starts getting cracked up and old though.
