This kind of material was named very good, but it is not as good as other foam materials like ORTHOLITE or PORON, just because it is made with some kind of new raw materials mixed with recycled materials and compress to a certain stiffness materials. 

But this kind materials is also very breathable and sold with very competitive prices, so that we can use them for some developing market. 

Most of this kind material can not be as soft and strong as new materials, it is harder.
