My son put this chair together and one of the seat boards that came assembled was cracked at the screw. We decided to go ahead with the assembly anyway. He grumbled a bit as the tool supplied was not hardened metal and lasted only long enough to get the job done. The chair is very comfortable and is easy for me to get in and out of with ease. I am in my seventies and this was a big consideration for me. Everyone that has tried it says it is a very comfortable chair. I would purchase again. (As information the email I received asking for a review did not work.)
