Thermophysiological comfort of duvets

The following webcast presents results of the German funded project AiF 19522 N “Bed Cave and Comfort”.

Within the project the interaction of thermophysiological comfort during sleeping and the bed cave was investigated. Duvets with different filling materials (down and feathers, polyester, animal hair as well as new developments) were examined according the classical, thermophysiological evaluation method for sleep comfort. Furthermore, a new evaluation method for duvets with the sweating, thermal manikin Sherlock (Newton type, Thermetrics) was developed. During the measurement, a realistic sleep situation can be reconstructed with the sweating, thermal manikin. All measured data were validated by monitored sleep test within a climatic chamber.
