My girlfriend and I have been sleeping on mattress toppers for several years now, and with our most recent move we were in need of a new one. This purchase was the most expensive out of all of the toppers we have invested in, and it was by the far the worst product of all that we have tried. I tried to get my money back on the first day and was told it was non-refundable. It gave us back pain.
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!
The "peaks" on the topper are the type that shrink down instantly. The 5.5" that this claims to be is really more like 2". It'd be worth it to spend more money and get one of the other toppers that are solid memory foam.
