There are 2 different types of latex rubber: Natural Latex Rubber (NR) and Synthetic Latex Rubber (SBR).
Natural Latex Rubber is naturally extracted from the rubber tree by tapping.
There are many types of Synthetic Latex Rubber: Each type has their own specific technical characteristics. In today's global latex mattress industry, Styrene - Butadiene copolymer (Buna-S Rubber -SBR) is mainly used for manufacturing synthetic latex mattresses. The method used to form SBR is by polymerizing two monomers, Styrene and Butadiene.
Products made from natural latex have higher grade physico-mechanical characteristics (tensile strength, elasticity…) in comparison to products made from synthetic latex. In addition, due to the specific chemical structure, products made from natural latex that are biodegradable at the end of their service life, thus causing no pollution.
A COMPARISON OF THE SPECIFICATIONS AND PHYSICAL APPEARANCE BETWEEN NATURAL AND SYNTHETIC LATEX MATTRESSES
The following comparison will be more accurate when comparing the chemical bond density after the vulcanization stage of natural and synthetic latex mattresses, as follows:

(*) Natural latex is more vulnerable to ageing than synthetic latex; however, Kymdan’s innovative processing technology has allowed our mattresses to last for over 25 years on average. In fact, research shows that the aging index of Kymdan mattress is more than 0.86 compared to other Natural Latex or Synthetic Mattresses that possess less optimal characteristics.
Kymdan mattresses are made from natural latex using a strict extraction process in order to have the finest natural latex. To produce a KYMDAN DELUXE Queen size with a thickness of 5.91 inches (15cm); generally, the raw rubber sap must be collected from 436 mature rubber trees.
Combining the finest quality natural latex, along with our very own pioneering technique for processing the raw materials, Kymdan has created unique products with the most outstanding quality:
