I'm not handy at all and easily put together the chair myself. It gets the job done if you need to sit for a couple hours at a time and is reasonably comfortable. If you need it for 8 hour use it might not be the best fit though.
Chair is very firm and offers great lower back support which I need after having injured my back. I feel comfortable sitting in it for long periods of time. While the seat is mesh and not particularly soft it is comfortable to sit on.
