I was looking for an ergonomic chair with good back support. The back support and headrest are very good. The chair would be ideal if it had a cushioned seat. The lack of cushioning becomes uncomfortable if you are sitting and working for more than a few hours.
I purchased this chair for the ergonomic features and it doesn’t disappoint. I do however have a small issue with the fact that it leans back so easily. Kind of hard to type like that but otherwise it’s a great chair.
