The chairs are very lightweight with riveted backs and seat slats.  They are painted silver, not a natural aluminum finish as we thought.  They are cheaply made with sloppy weld joints.  One chair was defective with weld droppings on the front rail (where it will scrap your legs) and a deep burn mark on one seat slat.  They were packaged fine and undamaged.  These will get minimal usage so we plan on keeping them, but not sure how well they will hold up long term.  We are working with Wayfair to resolve the one defective chair.
