The surface of the washable doormat measuring 50 x 75 cm is made of 100% high-pile nylon (polyamide), while the backing is made of 100% sound-absorbing and non-slip nitrile rubber. The Wash+Dry design mat is particularly flat and dense in pile, allowing it to fit under almost any door. It impresses with its color brilliance, is lightfast and colorfast, suitable for underfloor heating and for allergy sufferers, and is free from PVC. The design mat is completely non-slip and durable, making it suitable for both indoor and outdoor use. The washable and dryer-safe dirt-catching mat ensures hygienic cleanliness and can be used almost indefinitely. To enjoy your Wash+Dry doormat for a long time, we recommend washing it separately at 60 degrees every 2 to 3 months, and then drying it in the dryer at 90 degrees or air drying. This will reactivate the mat pile and straighten the fibers. For PVC floors, linoleum, laminate, and wooden floors, slight discoloration of the surface may occur due to interaction with rubber-coated mats. A size and color tolerance of +/- 3% may occur due to production.
