The GOLS-certified organic latex (CU863367) rubber used in our Avocado Green Mattresses is made from sap from our sustainably harvested tree farms in India and Guatemala.

The GOLS-certified organic Dunlop Latex is also STANDARD 100 by OEKO-TEX®: Class 1 certifications and eco-INSTITUT® label certified.

It contains organic ingredients and uses only 100% GOLS-certified organic latex rubber. It uses no synthetic rubber (SBR) or polyurethane foams.

The latex production process is simple. Step one is obtaining the latex milk sap. This is done by scoring the tree's bark with a knife so the sap can flow freely into an attached receptacle. Next, a tiny amount of stabilizers are added to prevent clumping before being concentrated in a centrifuge. Finally, according to the Dunlop manufacturing process that we use, vulcanization is required — in which isoprene units, which chemically make up the naturally occurring main component of latex, cross-link with sulfur and zinc oxide with the addition of small amounts of auxiliary agents (including dispersants and antioxidants). This is a required step using approved agents. When the latex is baked, much of it is burned or washed away, leaving only trace elements. This step aims to minimize any residual chemicals and impurities from the latex. The final product is made with ≥95% certified organic latex, the highest possible standard possible, and certified by the Global Organic Latex Standard.
