Bring the benefits of eco-friendly living to your toes with six flooring ideas, from cork and bamboo to sisal and wool. Wool rugs not only make beautiful hand-me-downs; they’re also woven from a natural fiber, which uses fewer fossil fuels to create. Natural fiber sisal rugs are durable, beautiful and affordable. Cork is a natural material that’s also hypoallergenic, making it a good choice for people with allergies and chemical sensitivities. Floor carpet tiles are an easy way to add a soft surface to any space. Made from nylon and a combination of natural fibers, such as wool and PLA (a derivative of corn), they’re recyclable and have some of the lowest VOCs, or volatile organic compounds, in the flooring industry.Terrazzo floors give rooms interest and sophistication. Made from recycled glass, tile or even toilets (really), terrazzo is the ultimate in durability. Design by eco-friendly designer Lori Dennis.
