Polymer elastic material is a type of medical polymeric composite. 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 multiple 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 waist, back and hip. So, it is called “Zero Pressure Material”.
