Flanking the beds along the wall gives a less traditional and more casual look, and open up more floor space, which is great for a child's room or smaller guest space. For my son's and daughter's shared bedroom (2 and 5 years) I put their twin beds along the wall as beds at night, an enormous couch in the day. It keeps the room clean and surprisingly Paris-salon-style, gives them room to play, and: they LOVE it.
