Honestly I can say this breed is amazing. It is firm, which I love and need. It also has a pillow top so although it is form holding underneath, there is a soft inviting and sculpting layer on top. I used to think the cooling technology was a gimmick but this bed has kept me cool despite Florida summers. I would 100% back this mattress and intend to buy again in about a decade. Only downside is that it cannot be flipped, but with high tech beds that was always unlikely.
