I bought this mattress topper because I needed something very comfortable to be lying down on several hours a day after having major surgery. I received it like a week before the surgery, and as soon as I received it we put it on the bed. We lied down and almost fell a sleep! The first couple of days it was a weird feeling, as it takes some getting used to it. At first I was talking to my husband and we both said the same thing, I don't know if I love it or I hate it!, because you get a little bit sinked in and once you sink in, it takes an extra effort to move to the sides. But after some days we really got used to it, and now we know we love it. It is superior comfort. It doesn't heat up at all, like some people say about other mattress toppers. If it was hot it wouldn't work for us, as Miami is hot enough!. Thank God I've got this mattress topper, because it made my painful recovery much more comfortable. More than happy with this purchase. It's like sleeping on a cloud, that hugs you, but a little bit firmer. It is perfect. I really recommend this.
