Chair Cylinder Removal Tool

I could not get the piston out of my chair with this tool. Maybe it’s me, but I read the directions 3 times and followed the instructions ( although they didn’t seem like they would work). I left the inside clamp(A) loose, as directed, and the upper one tight. But when I used the expansion screws, the two collars separated from each other, but the piston didn’t move. I tried tightening the inside collar, but that didn’t work either. It would make more sense to me if the inside collar went over the collar of the seat plate that the piston fits into. But the directions didn’t say to do that. It wouldn’t have mattered because the collars were too small to go around the seat plate collar. Overall, it was a great idea, but didn’t work for me. As a last resort, a lot of WD40 and a pipe wrench did the trick.

The Oasis Chair Cylinder removal tool worked exactly as expected. My chair cylinder was a bit rusted in and it took a couple tries but without the tool, I am not sure I'd have been able to remove the cylinder.

I tried two wrenches to remove the cartridge, but it was stuck fast.
This tool was beautifully designed, easy to use; and it popped the cartridge loose with little effort on my part

Tool worked perfectly as it should After getting 3 coupon offers before it arrived 5 since and now a BS survey over a stupid office tool
The tool works great this is a typical OVER kill of the client buy the company thinking their MUCH more important in life than they are.
Ya want a review ? YOU BUG THE **** OUT OF YOUR CUSTOMERS!!

From the moment I located Office Oasis on the internet right up to and including the installation of the chair cylinder replacement I was astonished.
Ordering was extremely simple, the parts were shipped and arrived in a very satisfactory timeframe, and the installation could not have been any easier with the instructions and the tool to accomplish with ease. Thank you Office Oasis, I've been spreading the word about you....and its all good!
