3D pillow is made of high polymer elastic material, which makes comfortable, good sleep for you! High polymer elastic material is a type of medical polymeric composite material. The material has threadlike structure. The inner part of this material is unique stereoscopic structure, which can form soft, comfortable surface and non-deformed 3D-- dimensional structure. After compression test of 250,000 times, it was proved that the body pressure could be turned into thousands of supporting points by the material, which can come into being the maximum comfort of body. So, it is called "Zero Pressure Material". The Advantages of the material 1, Good air permeability and heat shrinkable material 2, Good water permeablity, clean easily 3, high elasticity, reasonable softness and hardness 4,Durability, quiet design 5, Light weight, energy-saving and eco-friendly material 6, Recycling 7, Low toxicity during burning 8, avoiding bacterium The application of the product: Special design for the old people, long--term bed patients width:35cm,height:7/11cm
