This ironing mat is made of 5 layers of thickened material with a hard PP board in the middle to keep it flat and not deformed. It is anti scratch, waterproof, and high temperature resistant 200℃/392℉. The mat protects the table or bed from scalding, allows steam to pass through, and enables fast ironing. It has an insulating effect to ensure that clothes are heated more evenly during the ironing process, effectively protecting clothes, especially dark colored clothes and expensive clothes.
