I love this bed !!! It feels like you are sleeping on a cloud. My previous mattress was too firm and I was tossing and turning all night, plus getting up to use the restroom. I had horrible back pain from my old mattress.  I am a stomach sleeper and I was worried this mattress would be too soft, since it is more like a medium soft bed. But !!! With the 3 section zone support, it does a really nice job with support. The first few days, I slept amazing and then my back started to hurt. I gave it a try for 3.5 weeks and most of the pain went away. I still have the best sleep, I don’t wake up, I’m very refreshed in the morning. The only bad thing is I still have tinyyyyy amount of stiffness in my lower back in the morning. Debating if I should go got the wave that is a little harder. Not sure yet, since I sleep soooo good on this. Only reason I didn’t give it a 5. I wish it was a tiny bit harder in the middle section.
