Double Matress?

This is a long shot, but does anyone in Leeds have a double mattress that they are getting rid of soon? The one I have at my rented house is AWFUL - the springs stick through so bad it's getting hard to sleep. I can't buy my own as I don't know what I'd do with the old one until I left, and I can't throw it out because I'm not paying for a new one only to leave it here.

If anyone around gets rid of a matress at any point soon please let me know - it can't be worse than this one!
