Our natural Talalay latex is Cradle to Cradle GOLD certified. We feel that this is the most comprehensive standard currently available in the industry. In comparison GOLS (Global Organic Latex Standard) is very limited in its scope and doesn't even test offgassing of the finished product. The GOLS certification allows up to 5% of the formulation to be "non-organic" materials excl. synthetic rubber. It is impossible to make latex foam without additives (soap, sulphur, gelling agents etc.) so a lot can happen on the way from making the organic raw material into latex foam. We only use natural Talalay latex because it is superior to latex blends and Dunlop latex with regards to performance and durability.
