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.

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.

It works
Color: Black
Size: A/B
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.

Perfect Fit for my Aeron B Office Chair
Color: Black
Size: A/B
Fair value. The old foam insert had lost its cushion effect. This fits perfectly and brings new life to my chair.

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.

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.

Works for Mirra v1
Color: Black
Size: C
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!

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!
