We know about the existence of a tall forest tree which is of major economic importance because its sap-like extract (or latex) can be collected and is the primary source of natural rubber. Once extracted from the tree, the sap becomes solid, elastic and rubbery. The tree we are talking about is Hevea Brasiliensis, also known as Ca-hu-chu or ‘the crying tree’. The rubber tree initially grew only in Brazil; then, it was introduced in Asia (New Guinea and Malaysia).
Hevea brasiliensis is the source of virtually all the world's rubber production. Latex is a 100% natural substance: cutting the bark of this tree releases the latex which is then collected, preserved, and stabilized.

Thanks to its molecular structure, latex can be compressed or stretched to the limit without breaking or losing its original shape and this is the reason why latex is considered, and has become, the best material used for mattresses.
Latex is resilient enough to bounce back into shape, being supportive, comfortable and conforming to your body, so that your vertebral column can keep the best position during your sleep and that your blood can regularly flow through your vessels.
