Is it true that heat is likely to accumulate under featherbeds?
Down-and-feather-filled duvets are always capable to regulate the climate in bed. The idea of heat accumulation under a down–and-feather-filled duvet might trace back to the “bulging balloon bed” shown on the pictures in Wilhelm Busch´s classic children´s stories. However, scientific research on the subject “micro climate in bed“ revealed that high temperatures do not occur under featherbeds, even less under a down-filled duvet which is light by nature.
