Bending and flying away when got some pressure
After two months of usage the connection points are bending and flying away when you sit. I bought this by thinking Amazon is the seller but it is not different from the ones cheap fakes

Just pops off the rails immediately
This worked for about a day, but since then it's been unusable as the clips don't hold it on to the rail. When I lean back it just pops off and falls on the floor.

Pieza defectuosa
El producto muy defectuoso y de mala calidad, a la semana se instalado se empezó a romper. La pieza original que tenía la silla Aeron, duró 15 años, y esta pieza no duró ni 7 días!!!

Works as advertised. Lubricate as needed.
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.

Good item

Fit is poor
Product is OK but it sometimes pops out from the tracks so the fit is not good. When it stays in place it works well.
