I love this mattress and will never again have a mattress that isnt memory foam. I like a soft mattress and my husband likes firm, but we both like this mattress. Firmness It is a soft mattress, but still provides support. It isnt so soft that you just squish down into it. Durability My mattress is starting to sag a little on the sides, even though we have regularly rotated the mattress. It isnt really obvious when looking at the mattress, but if you sleep close to the edge of the bed, you can feel that the mattress has a slope. Feels a little like you are going to roll out of the bed.
