I often get night sweats and this thing really does keep you cool at night. Which is great because now I don't have to do the " I'm hot but cold so let's throw one leg out of the blankets and keep one leg in" and I'm not too hot to snuggle with my hubby and that's on top of the fact its like sleeping on a cloud. It's like I have a whole new bed. This will definitely be a Christmas gift for some family members. It was worth every penny!
