I dont have a latex mattress noddy, but I do have one of those "foam" ones that comes in a roll! Do you know them? They contain no springs and are made up of different layers of this foam type stuff. They come vacuum packed in a roll, and when you open it out, it springs into place. It is very hard to lay on, which is good for bad backs, as you literally feel it pushing into all those sore spots and giving you support. We paid �199 for our double, from a normal bed shop. Might be an idea for you.
