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.
