All the claims on the brochure are true! Until now, I have always used expensive duck down pillows and duvet. Since I am on wool, I have never slept better- the wool keeps me cool and warm and is very breathable. I have the wool pillows, duvet and matress protector. It almost feels as the the wool permeates throughout the whole room, keeping it cooler in the heat and warmer when it cools down. For years, if I ate food late at night, I would sometimes break into a sweat in bed during the night- now I don't. I am absolutely certain that this is because of the wool. I can't recommend wool bedding highly enough.
