Could be excellent, but manufaturing defect gave one chair an uneven base.  Fixed by attaching base to seat before tightening base halves together.  I suppose I could have fixed it with my angle grinder and smoothing out bad weld, but too lazy to get it out.  Seats are comfortable, we'll see what the future brings.  It was a bargain.  I can't really complain.  BTW The insurance was dirt cheap.
