When I first bought this, it was the end of summer and when I tried to sleep with it, I woke up in a pile of sweat...
BUT.. I tried it again in the winter time, and I have used it every night. I love it SOO much that I look forward to bedtime because it feels SOO great to have all of the weight on top of me.
10/10 for the winter (would recommend)
Not for me in the summer.
