Putting them together was no easy task. First chair took one hour. After that one I got it and the other three went quicker. For the money, they're okay, not great. They'll serve the purpose for a while. I didn't have the strength to rebox them to send them back. The front legs are uneven. Even when I adjusted the levels they still aren't level. I didn't realize they were made in China. If I knew that before I purchased , I never would have bought them.
