This chair was a good price but I did have a couple of issues. It claims to be good for long term sitting and honestly its not that comfortable for short term sitting. So long term sitting seems out of the question. In fact I am looking for another office chair. Also it says its easy to put together but some of the parts did not fit together well and I had to adapt. Its not a bad chair but not very comfortable.
I returned it after a week. It was not comfortable and it had a wobble to it that made it feel cheap. Also the hydraulics were faulty and the seat kept lowering overnight. So every day I would need to raise up the seat an inch or two.
