I bought a double duvet, medium weight and a pillow two weeks ago. I am definitely sleeping better and feel cosy (with a couple of extra wool blankets for this cold snap) but not too hot. I am so pleased with the difference in my sleep that I am now buying a mattress protector and an all season duvet. Guests will get the first duvet so I can get rid of the down duvets which make me a bit wheezy. I found the Wool Room website very informative, though several times couldn't always easily find something I'd previously read when trying to show an asthmatic friend the wonders of wool. There's lots of info and not brilliantly structured which is typical of small, friendly companies' web sites. I initially contacted the Wool Room by email and got a good helpful reply. A nice company to deal with, and a fabulous product. How come doctors don't recommend wool duvets?
