I chose my bed! To help emphasise this, I added long sheer curtains above my bed instead of art or other decoration. I read somewhere once that "hanging long curtains just below the ceiling that sweep all the way down to the floor is like putting a stiletto heels on a room," and while I hate stilettos, it works! While you want to keep your window curtains short, this trick behind your bed can help the ceiling look higher.
Another important note if you choose to make your bed the focal point: keep your sheets clean (hopefully you're already doing this in the traditional sense!). But what I mean by "clean" is sticking to a clean or plain pattern. Try to stay away from loud, busy patterns and instead try to coordinate the colours (remember monochrome?) and shapes with your drapes to match the flow of the room.
