Sustainability Score

While Plank uses CertiPUR-US certified foams and some eco-friendly materials, their transparency regarding manufacturing processes and supply chain is limited. Their parent company Brooklyn Bedding has made steps toward reducing energy consumption in their facilities, but comprehensive sustainability reporting and clear environmental targets are lacking. Labor practices appear fair but could be more thoroughly documented. The company shows room for improvement in environmental initiatives and public disclosure of sustainability metrics.
