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

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.

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 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.

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.

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.

I purchased a used Aeron C and needed to replace this part since it was disintegrating. I removed most of the screws holding the mesh in, lifted it up and pulled out the old foam. I used isopropyl alcohol and some paper towels to remove the old sticky gunk.The double sided tape on this new part was really tricky but I eventually peeled off the liner. Placed the new foam down and screwed the mesh back in.I would agree with others that this is just a tad too thick. So minus one star for that and the double sided tape.

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

The foam at the waterfall portion in my Herman Miller Mirra v1 was shot and it was hurting the back of my thighs when I sat in it for more than an hour. I read somewhere on Reddit that this cushion would work as the only other option was to replace the whole seat frame. I pulled out the completely worn-through portion of the pad, wiped the offending portion of the frame clean and crammed this in there. It's not perfect, but for 5% of the cost of the frame, I'd say it's 75% as comfortable. Also, it's getting better as is sit in it more. Would recommend!
