We are still comparing our new tempur pedic to the Sleep Number which we had for 10 years. So far , we love that we can move without affecting the other person. We also love that there is no "no go zone" in the middle! Wow! My only con at current is that we purchased a medium firmness. It seems really firm. We didn't want a sink into softness mattress... but, perhaps we should have went a bit softer. Perhaps we will "Adapt"!!!! LOVE our Cloud pillows!!!!
