The Soystainable Resilén Mattress is unique and environmentally conscious. Made with genetically unmodified natural soya oil, resulting in a highly flexible foam with a breathable open cell structure. The resulting airflow dispurses moisture, giving a fresh thermoregulatory effect. The mattress has no free elements or emissions making it baby safe. The soy memory foam comfort layer adapts to your body shape, reducing pressure points and is complemented by a progressive support layer.
