  • Perfect replacement for my Aeron C
Color: Black Size: 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. ... show more

  • Worked out fine. Size C.
Color: Black Size: C
Worked out fine. Like others say, unscrew seat, note positioning of old foam pad from edge, remove, clean off old double stick tape with goof off or other, clean with alcohol & dry, affix new foam, **register replacing seat by looking for a tiny triangular notch inside of chair seat groove and the corresponding triangle in seat edge you removed. Align and start by replacing seat screws at the front first. *To determine what size your chair is - A / B / C look under (or feel under) the top of the backrest. You will see, or find with fingers, 1, 2, or 3 small raised braille dots. 3 dots mean size 'C'. ... show more

  • Reasonable replacement to the OEM Herman Miller part
Color: Black Size: A/B
The foam insert arrived in good order, covered in bubble wrap with double sided tape already applied. The size is right for a B chair, it was the same size (width, depth, height) as the original. It seems to be a little firmer, but hard to tell as the old one had already perished. Only bad mark is the double sided tape, it was extremely difficult to remove the backing, and started to tear the foam in removal. I had to invest 10 minutes at least trying to correctly remove the backing. ... show more

  • Great replacement on my Herman Miller Aeron size C
Color: Black Size: C
My Herman Miller Aeron size C was bought used a couple weeks ago. It has a manufacture date of 04/26/2000. The leading edge seat pan cushion was the original so I figured I would change it out and get some padding restored. You will need a T15 torx bit or screwdriver to remove 12 screws holding the mesh to the seat pan. Once the 12 screws are out it simply pops out. My chair wasn't as gross as I thought it would be but it was still full of debris. I used a soft brush, shop vac with crevice tool, goo gone for old doube sided tape under original cushion and clorox wipes to wipe everything down. Many people complain about the included tape. I put on my reader glasses and picked a corner of the backing up with a razor blade no issues. If you go at it without paying attention to detail you will most likely pull it off like others have mentioned. I really don't see it doing a whole lot if you accidentally remove it, the mesh should more than adequately hold it in place once screwed back down. Once everything is cleaned up, new pad in place go ahead and start screwing the mesh back to the pan. I am old and half blind so this took me a little while. Best solution for me was to start at front corner. Squeeze the plastic pan into the groover and hold it while with my other hand, hand start the screw to ensure I got it back in the hole before screwing it in with tool. Just take it easy and do them one at a time in sequence around the seat pan. They just need to be tightened don't go crazy with torque as it is a steel screw into a plastic ring. Turned out great and the new cushion was well worth the effort as I am sitting here typing it feels great. ... show more

  • Perfect Addition for Size C Aeron Remastered
Color: Black Size: C
The back of my thighs rested on the front frame and would cause pain throughout the day. Added this cushion to the front and it works perfectly, fits perfectly, and gives me more of a relaxed seated position. It was difficult to remove the backing from the 3M Tape, but it's been sticking perfectly in place ever since. In summary, this cushion makes the my Aeron Remastered feel more like an Aeron Classic, worth every penny! ... show more

  • Fits Aeron Classic Size C
Color: Black Size: C
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.

  • Perfect size but there are a couple issues...
Color: Black Size: A/B
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. ... show more

  • Good stuff, fits an aeron remastered
Color: Black Size: A/B
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. ... show more
