Couldn't be happier with this buy.  It was easy to install with no hiccups.  We wanted the stairs to act more as a bookshelf than drawers, so we customized it and didn't add in the side panels to the stairs.  Now it's an impressive design piece when you walk into the room.  The twin size mattress height leaves plenty of room for a tall enough bed rail so we aren't concerned with the top person rolling off.  Also, the stairs are easy to move around if needed on either side of the bed.  I'm going to be sad when the kids outgrow it - it's really a beautiful piece.
