We got this because our pillow top went flat. The topper has helped with our back pain and is super comfortable. It is not too soft or too firm. I don't notice any increase in heat, but I would definitely get the cover; my husband does sweat and this stops the memory foam from absorbing it. It also does not cool the bed any. It tears easy; ours came with a few small tears where it had been folded. It is had to lift evenly so make sure you have about four people to place it up on your bed. The chemical smell went away after a week; we did let ours air out for over 24 hours before we placed it on our bed. It gave new life to an old mattress, and in my opinion has also helped with my husband snoring. We are both more comfortable and toss and turn less.
