It works!

My first attempt separating an older chair didn't work. I contacted Office Oasis, and they shipped out a new kit.
The new kit separated the chair from the cylinder after a few turns of the screws. The second kit also contained an improved design on the hex key, a little ball on the end, that stays with movement between me and the screw head.

The perfect solution!

I am extremely happy with the replacement kit that I purchased. The entire operation of removing the old cylinder and putting the new on took only a few minutes. The instructions and tools that come with the kit were perfect. I highly recommend the kit to anyone looking to save their office chair from the scrap heap.

Simply Amazing

I was a skeptic. In my mind, there was no way it could be that simple to change the chair cylinder. You proved me wrong, TWICE. I have two Aeron chairs. On one the cylinder was completely broken, top and bottom were apart at the base. The other chair the cylinder had a horrible rock to it, like it was about to snap off. In less than 1 hour, I had replaced both cylinders. Thank you, Thank you.

Extremely Happy!

Initially I was worried about repairing this chair by myself. The video provided and the repair tool included made this so easy. I’m 100% satisfied with this purchase!

Good as new!

Instructional video really helped. Install went pretty smooth. Only required a 5 lb persuader (sledge) to remove the old one!
