The Oeko-Tex 100 Standard comprehensively addresses the Human Ecology component of textile products. It evaluates and screens for any harmful substances present within processed textiles intended to come into contact with consumers. A manufacturer whose product meets the requirements set by the standard is licensed to use the registered mark or label "Tested for Harmful Substances according to Oeko-Tex Standard 100" on the product. Reverie® natural rubber components carry the Oeko-Tex Standard 100 certification.
