This mattress has the comfort of a pillow top that doesn't feel like your old pillow that constantly needs fluffing. But at the same time has structure that lets you know you aren't just sinking into a mold of yourself. I have lower back problems and was skeptical at first that this would end up just like sleeping on an air mattress, but surprisingly the mattress does offer support and great temperature regulation. I normally stay hot and my wife cold, but we both have been accommodated. I also don't toss and turn at night as much.
