These chairs looked great online and as long as you don't sit on them, they look fine in person as well. However the backs of the chairs I received do not lock into place whatsoever. Myself and my spouse tried to make the backs lock in for over an hour on each chair, and neither of us can make them work. Looking at the mechanisms, I don't see how these could ever fit together. We tried with the chair mostly together and tried again with the pieces separated, and they just don't match up in a way that they can lock together, so the backs are loose and you can easily fall backwards if you lean comfortably into the chair. I'm going to chat with customer service about it because this feels like I got a defective set somehow.
