The chair is pretty good quality. I would not recommend for anyone who likes to sit back while working. It bothered me the back of the chair only reached the bottom of my shoulder blades. It would be better for a chair for more active hobby and work where you are leaning forward more. The hydraulics on the char are solid. Good for use bad for trying to take apart and return. Might end up getting stuck with the chair because of it.
A really good chair for the price. Was easy to put together. It is much comfier than the previous table chair I was using! I love that the height is so adjustable.
