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

The replacement cushion felt great and was easy to install. I did have some trouble removed the self adhesive tape, however, I added some more on top of what was already there because I could not get it off without tearing the cushion.

I can feel an improvement compared to one without it, a more cushy feeling in that front rim area where most people complain about being painful. No idea how the original one feels so cant compare but I bought a B size and it fits a B size aeron remastered, some have said go with C for B size chairs but I feel like it would be too much, dont want too much padding causing you pain. Double-sided tape doesn't really seem to stick the pad, just came right off when trying to peel the first layer, but it does stick to the chair and once in place, it seems to keep the pad in place as well, I guess its easier for adjustments if needed as you can easily push up on the pad and move it around and once it sits back down the tape does hold it in place.

Ordered 2, one showed up in a few days, the other took over a week.... worked as expected, did have a double sided tape strip already attached.

Purchased a used HM Aeron Chair. The front seat pad was flat at crumbling. The chair is from 2001 and probably was never cleaned (well). I'm not sure what the others are doing but might as well do a good cleaning when replacing this pad. 2 bolts on each side removes the seat, unscrew all the little screws, take off the old foam pad and then wash the seat material and seat frame. After that, its time to reinstall the new pad and put it all back together. New pad fits perfect and feels great!

The shape fits fine for my Aeron B. Its the exact same size as the original. If feels firm yet a little fragile so it will start to crumble like the original cushion, I dont anticipate it will last more than a year or two. The only issue I have with it is the adhesive tape was old and would not peel back so I had to purcahse double sided tape. To apply my own tape I had to remove the existing tape and when I pulled it off it took some of the cushion with it. I hope they start to use better tape in the future.

This had fit my Aeron classic size B really well. The firmness of it had caused the installation to be a bit harder so I would advice putting on the seat pan and then maybe to try your best and insert it between the wedge. Feels nice on the chair and definitely makes a difference from the old and used one from 20 years ago!

Bought to replace a knee support cushion in my home office Aeron chair which was disintegrating after years of use. I spend the majority of my day in this chair, so its condition and comfort are important to me. This pad fit perfectly, was very easy to install, and significantly restored the support / feel of the chair. A simple and inexpensive upgrade to for any older Aeron. Highly recommended.

The pad is good and it fits and it’s comfortable for the prize but it’s a little smaller than expected. The size says A/B but it’s a little smaller for the B size chair. Wondering if I should try the C size but not sure some other reviews recommended C but I didn’t listen
