Honestly it felt nothing like the floor model did. It was an improvement over my last mattress that was a very cheap memory foam and was *seriously* harming me... but sadly not by much. After three months in it started sagging into the middle already. And I wake up still in relatively severe hip and lower back pain even if better than my last mattress. I was sleeping at a friend's house on a coach last week and somehow had less intense pain than this. It's got the issue where somehow it is both too firm and too soft; it's not firm enough to hold in the pressure points of the spine but it's not soft enough to feel relaxing or like my muscles can de-tense. I regret the money I spent on it!
