My fears, the heat generation of the ceiling (90% down, 10% feather) could be too strong, have not been confirmed after two weeks of use. Although it warms very well, I did not sweat. Since everyone has a different temperature sensitivity and the interplay between unused mattress and blanket also plays a role, of course, this can be perceived differently by different people, for me personally, the heat air was perfect.
The ceiling has only 24 chambers, ie the individual chambers are relatively large. In practical application, this does not bother, because the Dauen / springs do not collect in the corners and the stuffing was always distributed equally beautiful. Additionally, the ceiling is still there in the morning, where she was falling asleep (with me in the past is not always self-evident).
For completeness, it should be mentioned that the ceiling in the gentle cycle with mild detergent to 60 degrees washable. After my Kenntnistand this is normal standard.
Conclusion:
Such an all-year ceiling is naturally always a compromise. This is however in my view here is very well done and I can well imagine that I really will use on the ceiling apart from very hot summer days all year. I can therefore the ceiling as long as you look for a full-year ceiling highly recommend.
