More than 10 years I was under my cozy down comforter in 155x220. But since the purchase of a cold foam mattress I was sweating even in deep winter in bedroom temperatures of 8 degrees. I attributed this to the mattress, which is certainly one of the reasons. Then I read but that duvets generate accumulated heat. Below "isolated" So the KS mattress, above the down comforter. I often woke up in the morning drenched in sweat. Then I came by intensive googling on camel hair bedding. In short, I bought this ceiling. The first night was frustrating: Nix with cuddly, and the ceiling gave off a smell like an Anatolian herd of goats. In the morning, however, I woke up, my pajamas was kompett dry, no sweating, relaxed and refreshed. Although the ceiling stank still about 2 weeks after Kamel, but after that the smell verflogen.Die ceiling was warm enough even in cool bedrooms. I can therefore only recommended for those strong Schwitzer. Who slept under down previously, is indeed to be disappointed by the lack of "cuddly feeling", but I sleep a lot better than at any time since the exchange. The price-performance ratio of this ceiling is very good.
