From the very first night, this mattress has provided deep, comfortable sleep. I've never had to switch positions because something was hurting (my old mattress would frequently make my hip hurt if I were laying on my side). I have the pillows, too, and I haven't had any neck pain, either. I will always buy a Ghostbed when I need a new mattress.
Haven't had a bad night's sleep yet. Before I got the ghostbed me and my fiance were sleeping in different rooms just to get some sleep. Her bed was stiff as a board and mine was about 10 years old and sank in the middle. So when we tried to sleep in the same bed one of us was not getting any rest. But thanks to ghostbed we're back in the same room and sleeping soundly.
My husband and I both have back issues and our new Ghost Bed really helps with it. I highly recommend that others give it a try. You have nothing to lose!
