Review: Good piece to restore a classic Aeron - I found a classic Aeron at a local thrift store for $25 (SCORE), but it had seen better days. Aside from being filthy, this little football support as well as the pad at the front of the seat pan were shot. I disassembled the chair and gave it a thorough deep cleaning, lubrication, and replaced these parts while reassembling. It now looked and felt pretty much like a brand new chair. Turns out my chair find was a size B though and I'm a chunky monkey so it wasn't super comfy, I guess I have more of a size C booty, or maybe I'm just not an Aeron fan. I was able to sell it on though for a considerable profit, so I can't complain! Bottom line is this seems like a good replacement part at a fair price.
Review: Not as long lasting as i hoped for. - The part looks good and the chair feels better. The installation was easy and the part fit right into place. However, after about 45 days of use, the part keeps popping out of the mount. The retention mounts needs to be improved for better quality.

### ⭐⭐⭐⭐⭐ Good piece to restore a classic Aeron
*by J***Y on January 12, 2025*

I found a classic Aeron at a local thrift store for $25 (SCORE), but it had seen better days. Aside from being filthy, this little football support as well as the pad at the front of the seat pan were shot. I disassembled the chair and gave it a thorough deep cleaning, lubrication, and replaced these parts while reassembling. It now looked and felt pretty much like a brand new chair. Turns out my chair find was a size B though and I'm a chunky monkey so it wasn't super comfy, I guess I have more of a size C booty, or maybe I'm just not an Aeron fan.

### ⭐ Not as long lasting as i hoped for.
*by C***E on July 21, 2025*

The part looks good and the chair feels better. The installation was easy and the part fit right into place. However, after about 45 days of use, the part keeps popping out of the mount. The retention mounts needs to be improved for better quality.

### ⭐⭐⭐⭐⭐ Works as advertised. Lubricate as needed.
*by S***N on August 14, 2025*

Provides a moderate level of adjustable lumbar support that is a good option on Amazon for the Aeron classic chairs. You slip the piece into the grooves on the side of the chair and adjust it to the height you prefer. The other reviews mentioned the lumbar pad was popping out under use. To mitigate this issue, lubricate and clean the grooves as well as the C hook of the lumbar pad to allow the hook to move freely, otherwise it will eventually pop out and cause damage to the sides.
