Great product and service! I purchased" very light" wool duvet for my toddler as he was sweating enormously under microfibre duvet 4 tog even if bedroom temperature was reduced to 20. He definitely sweats less in his sleep, although I would say this light wool duvet doesn't feel like 1-2tog as it says on website. I feels more like 4 tog but I still like the product, the quality is the best I have ever seen. I also like that it is so easy to get it in duvet cover, it doesn't clump up as other synthetic duvets and don't have to puff it up every morning. Some might say it feels a bit stiff but I find it as a benefit because my toddler doesn't get tangled in it as much after his endless rolling in sleep. Thank you Woolroom!
