Kveenhof, if you look at the 9th pic (pic between the mitered corner and the can of paint) the on the interior long runners you can see the legs come off of that and then have a board that run parallel to the short side that sits on the floor for added balance. I wanted the bed to seem like it was floating so i tried to put the legs as far in as possible, but still keep it from leaning if a kid stood on the edge.
