They are a good price, but you are paying for what you get.  After having someone put them together with better bolts and line the holes up everything is finally together.  They also have a few scratches right out of the box.  Definitely need to check into the quality control of how they are being made.   
Maybe recommend having them already put together where all you do it set the chair on the base like they used to be. Customers would probably be happier
