Hands down one of the easiest chairs I have assembled in a long time, all the required bolts were already where they needed to go, I just needed to remove them and put them back when assembling the chair. It also has to be one of the best chairs I have used for comfort/support, most chairs I used before this one made me slide into an uncomfortable position after a few minutes of usage, haven’t had that issue with this chair and the lumbar pillow actually stays in place. If you have the disposable income, I would definitely recommend this chair for the ease of assembly and the comfort and support it gives.
