These stools are excellent!  The lady who said to assemble the metal to the bottom of the acrylic seat was so right. It is better to leave the 2 metal bars very loosely screwed before you attach to the partially assembled legs. Then add the screws and tighten all the screws (including those on the acrylic seats).  There was a bit of a learning curve on the first one but by the last one, it was 15 minutes total. (Note I didn’t use any of the swivel mechanisms.).  These stools are beautiful and easy to assemble!!
