 The formulation uses many of the same base components as the Dunlop formulation, but without gellation reagents.The result is marketed as a healthier alternative to petroleum-based foams since petroleum-based foams give off volatile organic compounds as they age.In the marketing of products such as beds that include "natural" latex foams created with the Talalay process, these products are sometimes characterised as 'organic' or as completely natural however there are different methods of producing Talalay that alter how natural the formula finishes.
