Heavy duty

I have been struggling with my weight for the past 10 years. Finding a office chair to support me is know easy task. I am glad I came across the cylinder for my chair now from office oasis that supports 1000lbs. It’s awesome, I can extend all the way up and it will not bulge. Thanks for helping us big guys out. I started at 390 and now down to 350 and still losing weight.

The best support in any business!

There is no better customer support from any company I have ever dealt with...NONE....NADA...ZIP....Zero. IF there was, they'd have to live in your living room 24/27. When they say they want YOU to be completely satisfied, they really mean it. Professional...all the way. Thank you guys for being the best and never, ever, change...you can't possibly get any better, but it won't surprise if you try. Good luck!

Make sure it is tight

Works great. The back collar slipped on me couple of times. After tightening it down worked as advertised. Great product

So easy!

I was shocked how quickly my son was able to repair my office chair. I asked if he watched the on-line video that I had watched and he said “nope”. He is pretty handy!
