True natural latex, without synthetic latex or fillers blended in, is simply natural foam rubber (from the thick rubber sap, or serum). Savvy Rest offers two different types of natural latex: Dunlop and Talalay. Dunlop, named after the method in which it's manufactured, is the denser, more supportive of the two. Talalay, also named after its manufacturing process, offers softness and gentle pressure-relief.
Savvy Rest natural Dunlop latex is certified organic in two ways. The rubber tree plantations are certified organic according to USDA (the U.S. Department of Agriculture) standards, and its processing is certified organic to the Global Organic Latex Standard (GOLS).
The Talalay is also certified in two ways. It has been sustainably harvested according to Forest Stewardship Council guidelines and has been certified as Cradle to Cradel GOLD, a measure of its health impact, level of material re-use, water stewardship, use of renewable energy, and social fairness.
