Perfect for work chair

I used this to replace my gas cylinder in my chair (which was quite difficult, but I wouldn't say that was the fault of this product so much as just that it's hard to get cylinders in and out of chairs). This cylinder doesn't work. It keeps raising the chair when I'm not sitting in it, then sinks to the bottom setting when I do sit in it. No matter what I do, I can't get it to stay down when I'm not sitting in it, and I can't get it to stay up when I am sitting in it.For the record, this listing says it's rated for 450lbs, and I weigh less than half that, so this isn't a case of me misreading the product's capabilities. Amazon requires you return the package to get a replacement or a refund, and since I'm lacking in transportation at the moment, I'm not in a position where I can pack this thing up and send it back, nor am I eager to get another one when this first one failed so badly and was so difficult to install.Do yourself a favor: DO NOT get this cylinder.
