The Cylinder Removal Tool Was a Lifesaver - Brilliant!

Below is a copy of the review I left on Amazon. Thank you for inventing the cylinder removal tool - it's incredible!

The cylinder pooped out on my office chair recently. I love my chair and spent a good amount of money for it and didn't want to get a new one. I'm pretty handy around the house, so I went on YouTube (my go to place) and searched for how to replace a chair cylinder. All 4 of the videos I saw told me to use a plumber's wrench to remove the end of the cylinder that fits into the bottom of the chair. Looked like a piece of cake to me, so I went for it! I'm a 78 year old women and my grip is not as strong as it used to be. I tried using the wrench but just couldn't get enough pressure on the wrench handles. So, I tried using my large vise grips. It still wouldn't budge!! So, I went back to YouTube and saw one entitled, How to remove a chair cylinder without a plumber's wrench." So, I gave it a look-see, and boy was I thrilled. It happened to be a video by the The Office Oasis Company that makes the ingenious cylinder removal tool which comes with the cylinder they sell. It worked like a charm, with little or no effort! The removal tool is simply brilliant!!

Great kit! Aaron chair {pre 2012} worked perfectly

Fantastic experience. Replaced cylinder on 1999 Aeron Chair. Collars were crucial in getting the chair off the cylinder which makes the kit so well thought out. The chair does sit about 1 inch higher than before but totally within a normal range [I'm 6 ft]. Bought on Amazon.

Cylinder works fine. Very fast one day delivery.

A No-nonsense Upgrade

Having performed a previous cylinder replacement a number of years ago I distinctly remember it as a very laborious and hard fought battle to remove the cylinder from the chair frame which I had hoped to never have to do ever again. The Office Oasis replacement and upgrade kit has now made this task extremely easy and almost fun. The wheel(s) upgrade and chair cylinder replacement procedure were both outstandingly simple and easy; even removal of the old height adjustment cylinder proved remarkably easy and effortless. I highly recommend this kit offered by The Office Oasis to everyone seeking to improve the functioning, comfort and durability of any office chair. A simply outstanding product innovation.
