The GOLS organic certified latex rubber used in our Avocado Green Mattresses is made from sap tapped from sustainably harvested trees in India.
The GOLS organic certified Dunlop Latex is also eco-INSTITUT® certified and tested by our manufacturer, Lien A in Vietnam.
It contains organic ingredients and uses only 100% organic rubber. It uses no (0%) synthetic rubber (SBR) or polyurethane foams.
It is manufactured according to the Dunlop manufacturing process, originally patented in 1929. The process is simple and energy efficient: natural latex sap, or serum, is mixed with a tiny amount of natural ash (3.5%, with zinc oxide), before it is whipped into a froth in a centrifuge, then poured into a mold, covered, and steam baked.
