Adore this. I suffered from night sweats for years, with no medical source. I tried everything, and then I had a stroke of inspiration and bought this mattress pad. I have not sweated in bed since, and I am overjoyed. I was also worried it would be too soft, but it’s a wonderful happy medium. The air the wool retains in it not only keeps you cool or warm in the appropriate seasons, it also creates a support system for your body, particularly your back. Easily my best purchase ever.
