How do natural, recycled, and conventional mattress materials compare environmentally?

Natural materials like latex, wool, and cotton can be renewable and biodegradable when sourced responsibly, while recycled materials help reduce waste and demand for new raw resources. Conventional, virgin synthetic materials are often the least eco-friendly due to fossil fuel use and end-of-life challenges, so eco-friendly designs aim to minimize their use or combine them with natural and recycled content.
