Love my new King size Elsa Upholstered Panel Bed in Patriot Blueberry.  It is a true navy.  It is beautiful and expensive looking.  It was confusing setting it up as each part came with different directions, and some of the directions sent were missing pages, but I prevailed (with help).  I have a standard box springs, and it does show above the upholstered side rail.  My box spring is black so it blends well.  Not sure if I will end up using a bed skirt or cover the box spring with a sheet or something.  By using a standard size box spring, there is no gap between the top of the mattress and the  bottom of the headboard.
