### ⭐⭐⭐⭐⭐ Great replacement and easy to install - All tools were included
*by M***S on January 11, 2023*

I've had my Aeron chair for nearly ten years. I picked it up used to replace my crappy old chair from one of the big box stores when it finally gave up the ghost. So recently I heard a "crack" and saw that the back frame of the seat had finally worn down and broken. I was beside myself. I didn't want to buy another chair, so I looked for repair shops in the area. One of the shops referred me direct to this product page and said, "order this, and if you want, I can install it." So I did. Fast forward and, still sitting on the broken seat, busy with work, I decided to look up what the repair entailed. I found a tutorial on youtube. Four bolts for the seat. Two nuts to transfer the j-bars. I figured I could handle it. This replacement seat kit came with the hex wrench needed to undo the seat, and a fitted wrench and a T25 torx driver to quickly transfer the j-bar. It took a few minutes, and a bit of leaning in because the bolts were really in there, but the replacement was easy. I literally didn't take out my toolbox because I had everything I needed in the kit. Really well designed chair and replacement was super easy. Five stars.
