Sustainability Score
62%
While MattressInsider uses some eco-friendly materials and maintains domestic production, they lack transparency in their supply chain and environmental impact reporting. Their use of CertiPUR-US certified foams is positive, but they could improve their sustainability documentation and commitment to renewable energy. Limited information about labor conditions and minimal public environmental goals affect their overall sustainability standing.
