Really great advice prior to purchase. I had already purchased a cheaper "wool duvet" from elsewhere however it actually isn't really a wool duvet because it has some man made fibres which still made me really hot in bed. So after this experience I did some more research spoke to 2 companies about their wool duvets, I decided on the wool room because of their honest advice. We purchased the deluxe two season duvet, I can honestly say I haven't ever slept so well. My partner who frequently awoke in the night with our old feather duvet and would then be unable to get back to sleep, hasn't had a broken night sleep since we've had our new wool duvet. I have since bought 4 single Classic Duvets to replace our sons feather ones too, the reports back from them is a 10 out of 10 night sleep. Thanks Wool room
