This is my first ever memory foam mattress.  At first it seemed weird because you can't slide around under your sheets as you can with a conventional mattress.  After the first night's sleep though, I was hooked!  I have honestly never slept so comfortably as I do now.  I fall asleep within seconds of laying down.  If you're trying to catch up on all your recorded TV shows, this is not the mattress for you; you will succumb to sleep before you can even get through your show's opening credits lol
