Update 3/18: Wayfair customer service is awesome!  They were going to send out a replacement set, but we now have everything.  We haven't finished putting everything together, it is difficult lining up some of the screws (any recommendations other than leaving them all loose would be welcome),  but it is going to be exactly what we wanted.

As we have only received 2 boxes out of 5, we are not happy with our purchase.  The tracking info on the last 3 says that they were picked up by the shipper on March 8 (which was supposed to be the delivery date), that tracking would be updated within 24 hours, and it hasn't been.  I will be calling on Monday.
