Firstly, the chair was well packaged upon arrival. All tools are provided, but it helps if you have your own. The build didn't take too long (roughly 10-15mins). It comes with a variety of adjustable features to adapt to your personal comfort. I tend to work at my desk for 6-10 hours a day, so comfort is key. The only issue I have is with the lower back support. I find it presses a bit too much on my spine, so to get around this I use a small pillow as a separator. Apart from that, I am very happy with the chair.
