My mum & dad have one and mum swears by it, she was going to get us one for a laed wedding present but I had fallen pregnant by then and it wasnt recommended at that time, you can also get one with a woollen side as well (although a bit more expensive) but they are very very nice to sleep on. Havent slept on one for any length of time (as in more than one or two nights) but they have either a 30 or 60 day return policy also. Might be worth while giving it a go and see what it is like
