I'm a side sleeper and I move throughout the night, but I also have some back problems from some car accidents, so I needed support with some "give". This mattress has it all. A nice soft top layer to allow some room for my shoulder, but enough firmness fo give my back some much needed support. I fall asleep fast and sleep well, and look forward to naps and bedtime. Even my cat sleeps on the bed more often, and the motion transfer reducing technology means I don't get rude faces when I get up now.
