Organic latex has to do with how the rubber trees are grown and how the raw material is processed. Plain natural latex is subjected to much less stringent rules, and thus can’t be labeled organic. Latex with an organic label has to be grown with few to no synthetic pesticides and fertilizers, and it must be processed with as few chemical additives and synthetic agents as possible. Dunlop latex and Talalay latex are the two basic types of latex that go in mattresses, and they both are organic, but have different feels—Dunlop is firmer and denser while Talalay is softer and squishier.
