We've had our Tempurpedic for about 4 months now and I must say I am loving it. I'm not sleeping all night (as I've said before, I'd need to be knocked over the head to sleep all night), but I have noticed I haven't had as much back and/or neck pain. However, I am starting to get a little achey here lately. I believe this is because I never did go get the mattress cover that is supposed to help keep you cooler. And with the weather warming up around here the bed gets super soft. It says the room should be around 65 degrees (or cooler) for best results. Well, that doesn't happen when we do not use the AC. But I am still very pleased with it!
