These chairs are impossible to assemble! The parts do not match and if you want to kill yourself with frustration and waste a lot of money when you give up go ahead and buy them.  I am so disappointed as I ordered the same chairs a few years ago and they arrived in only 2 parts for easy assembly, not a thousand with the worst instructions in the world.  Of course, by the time I have gotten around to sending them back my 'window to return' has closed.  Wayfair, I'm very disappointed in this and likely will not make futher purchases with my business account.
