This is far an away the best bed I have ever owned and can't recommend it enough! I have always had to sleep on my stomach but have been able to sleep on my back and side on this bed. No matter which position I sleep in I wake up without back pain and refreshed. There is just the right amount of cushion and firmness. I am 5'11 190lbs and my wife is 5' 115 lbs and both of us sleep very comfortable on this bed.
