HORRIBLE chairs! I’d rate it zero stars if I could.  Everytime it rains or they get wet, they all leak rust from multiple parts. I have to hose off my stamped concrete or it will be stained rust! EVERY SINGLE TIME! 
Tried to return but had gotten rid of the boxes already when I figured this out. Wayfair should have paid to take them for a full refund. I sent pictures of all the rust as well as proof.
