I am selling our double size (4'6") mattress, it is from Bensons for Beds and is their Easi Pocket Memory 1050. This is currently in the sale for £359.99. We haven't had this very long, it has always been rotated as per the manufacturers instructions and has always been used with a top quality mattress protector and looks brand new. You are more than welcome to come and try it first.
