Was disappointed to find that the mattress was both uncomfortable and very warm to sleep on. Our old mattress wasn't bad but we thought that we would treat ourselves after watching the television adverts. We have not had a good nights sleep since and wake up frequently during the nights in a sweat and with aches and pains. I wish that we hadn't got rid of the old one, if we still had it this one would be going back. Don't believe all you read!
