I purchased this product because of back problems and I have tried every mattress except the foam ones. So, I thought that I would try a foam topper first to see if that would help. Too soft for my husband. I like the feel and the comfort, however it is very hot. I can only sleep on it for about 3 hours before I wake up too hot and have to go to another bed. My back doesn't hurt as bad, but I can't sleep on it all night. So, if you always get cold at night, this one's for you; no need for an electric blanket.
