KetofaLumbar Support Pad Replacement for Herman Miller Classic Aeron Chair - Size C: Medium,Black

Decided to trust the positive reviews since there aren’t a lot of inexpensive choices for replacement lumbar pads for the original Aeron. The original factory version started failing after just a few years, and I limped along using duct tape to seal the tear in the foam for quite a few years. Install of this replacement was simple and quick. Have been using for a couple months now and no issues. Even if I only get a couple years out of it, it’s still worth it given the low cost and ease of install. And yes, the support is sooooo much bettter now! Definitely worth a try.

The back rest keeps falling off when you lean in. The only time it stays if you position it lowest part of the chair (meaning no back support )

Easy to install make sure to get the correct size I ordered mine twice because I picked the wrong one the first time

it's a great product at a fraction of the cost of OEM. it does have the tendency to slip a little on the frame, so i just make it a habit to push it down about an inch every other monday morning before it sit in the chair. if it goes 1-3/4" it can actually pop off one of the frame rails (not a big deal, but can be an annoyance to have to pick it up and re-mount it.if it stayed locked in place, it would be a 5-star review

Just as good as the original one twenty-two years ago.
