I answered a similar question on another thread but the short answer is that it's probably more consistent than Big T foam. I've heard from more than a few people who owned Big T that if you own more than one mattress they don't feel the same. I think it's because of different atmospheric pressures on the different days the foam is poured. Comfor-Pedic foam is said to be poured under controlled conditions so it all feels the same.
