This duvet is heat regulation. Balance between body and mind. During their sleep, their body constantly changes of temperature. Depending on the sleep phase it gives off heat, or take the heat on. This continuous process of heat regulation is often the cause of a restless sleep. It was developed to store the excess body heat and-when your body asks-off again. This creates not only a constant temperature of their body, but also an optimal balance between body and mind. This duvets and pillows have a lyocell fabric with Outlast ®. For the synthetic fibre filling is the resilient 3D Polarsoftvezel processed. The raised edge ensures that the duvet is airy and smooth around the body, every night.
