While Mattressonline.co.uk offers some eco-friendly products, their overall corporate sustainability practices lack transparency. They have basic recycling initiatives for old mattresses but provide limited information about their supply chain ethics and environmental policies. Their packaging and delivery methods show room for improvement in terms of environmental impact. The company needs to develop clearer sustainability goals and better reporting of their ESG practices.
