My mattress was very firm. This is just what I needed to give it a more pillow-like and soft, feel. Very comfortable. I tried it both ways, tips up and down. I prefer tips up for more therapeutic/sunken in feel, but I liked having the option. The bonus cover is a great addition too. Adds even more padded softness. Both the memory foam and cover seem like good quality, but time will tell. I do agree with other reviews that it doesnt draw heat away, but rather the opposite, unfortunately and I'm not sure its really a "gel" memory foam. However, I disagree with reviews about the smell. There wasnt a strong odor. I put it right on my mattress just a few minutes after it fully filled out. I also found it strange that despite being advertised as "Comforpedic", the box was delivered unmarketed. The products had no logos or branding on them. There was instructions/about the products/ thank you though. Overall, I am pleased!
