It's a hallelujah moment. I get up and I'm able to walk first thing in the morning! It's encouraged me to go on a diet too. I'm a fidget and it's most annoying waiting for your bum dip to pop back out when you have rolled onto your tummy but.... It may not feel the most comfortable getting your position at first but once asleep it is lights out for the night and when you get up nothing hurts. Brilliant.
