I love the chairs, but i noticed after putting together, that 1 bracket on 1 chair was broken on bottom, back part was leaning on one side, so i finally got back there today and looked and sure enough, bracket is broken on bottom , by hinge. I didnt get extended protection but i am now. If you buy from wayfair protect yourself and get the added protection. Otherwise awesome chairs, helps me everyday and im disabled.
