This chair was easy to assemble and give much better back support than my old one. I work remotely full time now and have noticed that my backaches and tiredness are less with this chair.
we took the first one back because of noise in the air chamber. tried a second one and the wheels on that one wouldn't roll. took that one back and purchased somewhere else
This chair makes me feel like I'm falling forward. The only way I don't feel like I'm falling forward is if I adjust the chair all the way down where my knees are bent at a 90-degree angle. If I raise the chair to is comfortable working height to fit my desk I feel like I'm sliding out of it. So now I use something to hold my feet up so that I can sit a little bit more comfortably. I'll probably soon get rid of this chair.
The chair was easy to assemble and adjust. It is firm to sit in and moves easily. The black finish blends well with my computer and space. I recommend it highly.
