Sustainability Score
62%
King Koil demonstrates mixed performance in sustainability practices. While they have made efforts to use CertiPUR-US certified foams and implement some eco-friendly manufacturing processes, their transparency regarding supply chain practices and comprehensive ESG reporting is limited. The company has basic labor standards but lacks detailed public information about worker conditions in their global facilities. Their environmental initiatives are modest, focusing mainly on material compliance rather than innovative sustainability solutions. More robust sustainability reporting and clearer environmental commitments would improve their standing.
