Place I bought my chair from was supposed to supply these and didn't. I was using the vinyl ones until they cracked and then realized they weren't leather. These are much nicer and look like they'll last a good long time.

Really like the look in the feel of these on my chair, very comfortable and durable. Much better than the plastic models.

I got this as a replacement to the OEM leather arm pads I had on my Classic Aeron chair, as the leather had cracked from over 7 years of flexing as I got up out of my chair.These arm pads, as others have mentioned, have a much, much, much stiffer foam core that's much closer to the firmness of the OEM vinyl arm pads, although this one is covered with leather, and the front edge of the arm pads are squared off, and the top surface is much flatter.That being said, since I only really touched my arm pads when I got up from my Aeron or readjusted my seating position, I think that firmness is desirable since it reduces the flex that caused my previous leather arm pads to crack, so I'm perfectly fine with that change in firmness.I would just say that the only issue I had with these arm pads came from installing them, as the screw holes aren't pre-tapped, so I would recommend using the armrest screws to tap those threads before attempting to install.

They are really easy to replace and much more firm than the original ones. But the trade off is worth it because it's soft leather compared to that vinyl they use on the original ones.

The leather looks much better than the original plastic armrests for this chair. The armrests are much stiffer than the original arm rests but that's better in my opinion. When you remove the old armrests (two screws under each armrest) keep those screws because you'll need them for the new armrests. Although the screws don't look like they'll tap just apply enough pressure and they'll thread into the new armrests properly (make sure the new armrests are flush with the bracket first).

These would not fit on the arms of my chair no matter how hard I tried. Even pushing down on the arm with my full weight wouldn't get it to fit enough for the screws to reach the holes. The leather seems nice quality, however it seems like it could use better padding. Since they would not fit the arm, I have no idea how it would perform on every day use.

These were absolutely perfect to replace the torn arms from my Herman Miller chair. They’re super comfy and we’re super easy to install.

**UPDATED after one week of use**I have been using the original leather armpads for about 5 years on my Herman Miller Aeron. They have been used heavily, and the leather on both arms has cracked and worn. I was looking for replacements, and actually liked the look of these better than the OEM replacements, so I decided to try them. They were very easy to install and look nice on the chair. They fit just like the OEM arm pads. The texture of the faux leather is fairly nice, and the stitching looks good. On the underside of the pads you can clearly see lots of staples holding the leather in place (not something you can see in the product images) and not all of the staples are fully seated. So while I can't speak to the long term durability of these, the build quality seems only OK, perhaps on the cheaper side.The main draw back is the padding. The OEM pads have nice, squishy, soft, comfortable padding. These, by comparison, are rock hard. Moderate pressure and they hardly compress. If I really squeeze one with my thumb, I can actually tell that there's a lot more foam that you might realize at first. However it's so firm that you'd think there was no cushion at all until you press hard. I've only had them for a few minutes, but so far, they aren't particularly UN-comfortable. So honestly, this may not be a draw back if you'd actually prefer a very firm arm rest. There is some padding, it's just very firm. However, I rather like the soft cushion and these are just too firm for me. I will likely be returning these, and instead going with the OEM pads from Herman Miller.Update: After using these for about a week, I have decided to keep them. I also ordered the OEM replacement pads from Herman Miller via Amazon to see which I liked better. Assuming they weren't fake, they weren't much softer than these. I also think they look worse, as they had a rounder shape to them and didn't look as crisp. After using these for a week or so, they just don't bother me like I expected they would. The texture is nice, and I don't seem to be bothered by the firmness at all, even if I put a good amount of pressure on it. Hasn't created an pressure points or anything. The biggest gripe I have now that I've used them is that the stitching on top of the arm pad is right where I rest my arm, so when wearing short sleeves I feel it, and would prefer it be smooth. Normally leather should have a groove pressed into it first before you stitch, so that the stitching is sunken in as to create a smoother surface. This bothers me slightly but it's not that bad.So I'm going with the cheaper, better looking option. I changed my review from 3 to 4 stars.PROS:Fits wellEasy to installLooks greatTexture is niceCONS:Stitching around edges of the arm pad creates an uneven surface that can be felt on bare skin.On a cushion scale of one to ten, 1 being a down pillow and 10 being a rock, these get an 8.
