I fell asleep easier than any other bed I've ever slept in, but I woke up with lower back pain. I returned it. I wish this bed was just slightly firmer. 

All I want is a bed that lets me sink into it but also supports my lower back. 

I weigh 175 lbs and I'm 5'10"; side sleeper that tosses and turns. This bed is is very nice, but not for me sadly
