Rearranging

I have been trying to rearrange the furniture in my apartment. It's not going so well. I am limited by the fact that some of my shelves are attached to the wall and I really don't want to take them down and move them. I am beginning to suspect that I need to get rid of my chair-and-a half. It is comfy but has been mauled by the cats and is suffering from years of hard living.
Here is the arrangement of the moment. I don't think it works but I'm at a loss where to go. Try to ignore the pile in the right foreground.



The chair just doesn't seem to work there in the corner. And it leaves the desk and the table too close to each other. I had originally had the bed along the window wall but it cut off access to one of the windows. The desk was in the right corner and cut off access to that window. If I get rid of the big chair and replace it with something smaller I could move the desk further to the left or even swap the desk and chair. (I tried that already at the moment and the current chair does not work in the middle of that window wall.) The table would not seem so trapped in the corner then. The table used to be where the bed is now with the chair next to it. I've been staring at the current layout and just don't know where to go. Any suggestions?
