Cracks on 2 supporting members of chair which I attempted to repair with epoxy and a metal plate. Picture of 1 repair is attached. One leg of a chair was also shorter than the rest (fixed it with a felt pad). 

Wayfair customer service was amazing in sending a replacement chair. Otherwise, screw length was fine and assembly was easy. An item worth noting. 4 chairs were sent at the same time, but FEDEX lost 1 for several days. So do not assume you will receive all items are the same time even if they are identical and get shipped out at the same time.
