This ended up being a disaster.  It looks like the manufacturer screwed up putting the pieces in the boxes.  The frame itself has mismatched pieces, the head and foot rails are King width, but the side rails are only Queen length, 77' inches instead of 83' as stated on the website description.  But the real kicker was that the footboard and headboard  are only Queen width instead of King width.  What a mess!

Thankfully Wayfair is giving us a complete refund on this one.
