We ordered the headboard in King.  It's great!  Very sturdy; I lean back on it while watching t.v., and it doesn't move.  The headboard comes in 3 pieces:  the top decorative part of the headboard and 2 'legs' that we used a rubber mallet to securely tap in to the bottom of the headboard.  The 2 'legs' were then attached to our bedframe with hardware included with the headboard.  Very easy to set up.
