We use the Tempur-Pedic AdvantageBed for six month now and cannot imagine to sleep on a different mattress again. We tried all the other kinds but had to stay within a budget and are super happy that we made the decision to get one. The velour mattress cover has a two year warranty, is removable and washable and Allergen and dust mite resistant. The mattress and platform foundation have a twenty year warranty. The first ten years full replacement and the second ten years prorated. My husband got serious back problems and does not experience as much pain as he used to before. I am currently pregnant and enjoy this mattress very much. You would not realize how nice this mattress is until you get to lay on it and relax and then you feel the difference between the one you used to sleep on and the tempur-pedic. We are very pleased with this mattress and would spend the money for it all over again. Definitely a number one mattress.
