Mine varies. It is either really tidy (that's how I like it), or kinda messy if I can't be arsed to tidy it, even though it annoys me when it's in the latter state. It only gets REALLY messy when I'm in the middle of a "military room-sorting" thing, which is where I put everything on the bed and sort out what I'm keeping and what I'm getting rid of. Then half way through I get tired and can't be arsed to finish it.
As I write this, I've nearly finished tidying from the last time I did that.
