It is a two-piece duvet made of microfiber, zusammenknöpfbar. A ceiling is thicker, the other very thin. Both together is lightweight and feels soft and smooth. Best processing. I have the thicker blanket used as a blanket, the thinner with Lake tensioners as sheets on my 1.20 m wide bed, because I use a viscoelastic pad that is me cold and uncomfortable with an ordinary sheet. Since I use the upper bed with duvet cover, the buttons did not bother me. Now in April you need the thicker blanket necessarily, and I think that we thus also in the few really hot days still copes in the summer. In the fall I will button the second ceiling to and my old mattress - also made of microfiber - Fit again. So far I have natural fibers (wool / llama wool / cotton) preferred as blankets, but now find that microfiber is bad in any way. This material also absorbs moisture very well, dries well and is - which is particularly pleasant - washable. I can absolutely recommend this quilt.
My cat lady Annabell agrees with me completely. I had the bed not even respect the right, as it was already out and did not want to budge from the spot. And she lay there until morning - stretched pleasurably. We both felt very comfortable.
