As described online. Much more soft than our prior mattress. Only slept on it for a few days thus far and for me, with a lower back issue, I'm still having problems staying asleep. Maybe will be better in another week or two. My wife says it's so good to finally get a restful nights sleep. It would be nice to have this model a bit thicker however, instead of having to buy a separate 4-6 inch riser box. Have to replace sheets to fit properly.
