What the What?!?!?

Ok, I've been a self-proclaimed handyman for a lot of years. Anyone who has done DIY projects knows for a fact, every project takes twice as long and costs twice as much as it is supposed to. Well, for once this was proven incorrect!!! I came to fix my wife's chair with the cylinder replacement kit and new wheels fully expecting things to go well awry of the instructions that were provided. To my relief and surprise the replacement went exactly as it was supposed to. I am very happy with the parts that were purchased from Office Oasis. The instructions were easy to follow and went exactly as planned. I highly recommend this for anyone who is planning on getting a new office chair that won't stay up or no longer works. Saved us around $100.

Easy to use product

The product was easy to use and the instructions were clear and easy to follow. Fixed my sinking chair problem and also it has my chair sit much higher than it was, allowing me a much better range of heights for my desk.
