Viscoline is an open cell polyurethane flexible foam that unfolds its thermo-sensitive properties when it comes into contact with body heat. It molds itself perfectly to the human body to relieve pressure.  This improves blood circulation during sleep. Deep sleep begins sooner and lasts approximately 50% longer because there is less “natural” tossing and turning during sleep. 

The pressure relieving properties are also successfully applied in medical applications to prevent decubitus.
