Natural, pure and elastic, caoutchouc remains the most important ingredient in manufacturing orthosomatic mattresses and orthocervical pillows. Natural rubber, before being processed into a more stable form, occurs as a milky juice extracted from the caoutchouc tree growing in tropical climates. Once it arrives at the COCO-MAT factory, it is cleaned and stabilised using the Talalay method, which ensures that its natural properties are safeguarded to a degree of 96%. Once stabilised, it is cut into separate sheets of rubber. Natural rubber breathes perfectly and has a long lifespan.
