A few years into our marriage we bought a California King motionless Pillow Top Water Bed. It's the size of Ohare airport! I have to say, it is a solid good night sleep. If we ever have to stay at a hotel, we complain every morning for one of us stealing the covers, or smacking the other in the face..lol

So I believe this article. Good Night sleep is important. But if you have the room, get a california King.
