Decorating a Small Room...?

I would like to get a full size bed (I have a twin) and that will take up a lot more room. I also have a dresser that is not too large, but my desk is huge. I was wondering if I could use a smaller table to store my laptop, a lamp and some school supplies. Nothing too extravagant or pricy... Any thoughts would be gratefully accepted. Please link any specifics... Thanks!
