Waited a full three months for the other shoe to drop before weighing in on this mattress. Could have written it after the first night. Years of bad mattress-caused morning backaches disappeared overnight! Slept through without tossing and turning - amazing. I'd say it's about a 6 on the firmness scale. Firm enough for support but pillow top enough that it feels soft against my body. It's a good 6 inches HIGHER than my old mattress...sorta have to "climb" into it but I'm only 5'5.
