I love this mattress, and my husband likes it a lot. We got a firm and we are both sleeping better than we did on our regular mattress (innerspring?). I tend to get hot while sleeping and this mattress helps keep me cooler. And when one of us rolls over, which we both have always done a lot, the other barely feels any movement, and not at all if asleep. I think we both are rolling over less often, too. Just a warning, though, it's not bouncy at all, so if you like bouncy sex, use a spare bedroom. :)
