This mattress pad transformed my memory foam mattress! My mattress was already one of the most comfortable I’ve ever slept on, however, I was sweating every night in my sleep. That all changed when this mattress pad arrived. I took it out is the box, laundered it following the instructions in the package, and put it on my bed. It’s been about a week and I am in love! I don’t want to get out to the bed in the morning.
