This is truly a beautiful set.  I wish there was a way to order extra pieces as one more seat would be fantastic for our needs.  It did not take as long as others stated to put together.  About 2 hours to assemble the entire set.  However, directions were not clear; after the first piece is done, you kind of get the common sense idea to how it all lines up.  
The only problem we had was that when we ordered it, it said it came with 2 sets of cushion covers as well as numerous reviews stating the same.  When we contacted Wayfair about the extra set, the description had changed to "1 set".  Disappointed in that but definitely not the purchase!  Delivery was also very quick!
