I have had it about a week now and so far so good. It is a little stiff but I think I am just getting used to it. It was pretty easy to put together but the instructions they send are bad.
very comfortable and supportive chair. did not attach the upper neck support as it was too low for user's height. would be nice if the neck support was adjustable (able to raise)
Purchased this chair as I was beginning to have back issues due to remote work. This chair did the trick and no more back pain. I had tried other chairs in the store and this was the most comfortable yet supportive one.
