Queen size mattress in good condition. (King's Cross WC1X)

This was given to me by another Freegler, but it wasn't suitable as it wasn't deep enough. I'm based in King's Cross. Just let me know when you can collect from a ground-floor flat from midday onwards. It looks buckled now because it has been lying upright against my bathroom window in the bright sunlight for some weeks now. It will return to its original shape once it is laid flat again.
