I love the chairs and they are great for the area we planned for them.  But, when the chairs arrived, one of the boxes had loose hardware.  Apparently when assembling the swivel apparatus on the bottom, the first two screws, nuts, and bolts were secured improperly and the other two could not be secured, so, rather than start over and complete the assembly, the person just threw the loose hardware in the box and sealed it.  Poor work ethic personified!
