All Milliken & Co. area rugs are made of 100% Stainsmart Nylon and are approximately 1/2 in thickness. They have serged edges to prevent fraying and the backing consists of a tightly woven polyurethane blend. Milliken’s patented Stainsmart Nylon is a dual-action stain protection technology that repels and releases stains. Due to the custom-made nature of Milliken’s area rugs, please read our return policy before purchase as return shipping and restocking fees may be applied to non-claim returns.
