Safe & Healthy Chair Mat MaterialOur range of chair mats are made of up of different materials. We make sure to provide you with the healthiest options. In particular, PVC has gotten a bit of a bad rap over the years because of the harmful plasticizers often used to give it its flexible nature. The PVC used in our mats is free from phthalates, which is considered one of the most toxic plasticizers, perfect for light/multi-purpose home use. So you can now benefit from the wonderful strength and flexibility of a PVC chair mat without worrying about toxic chemicals filling your air space. What’s not to love?
