Made in Europe: the floor mats are produced in our own factory in Europe, have a back made of 100% nitrile rubber and a surface made of robust nylon pile (50% polyester (100% recycled) 50% polypropylene). Important product details: the Dune mats are particularly flat and dense in the pile, sound-absorbing, non-slip and non-fading. There are also 2 years manufacturer. Indoor and outdoor use: Dune is designed with its coarse 3-dimensional structure so that the water is collected by deeper channels and drains in it. This makes it perfect for outdoor use. Visually appealing, it can also be used indoors. In addition to the functionality, the sustainable use of recycled materials is particularly noteworthy. Premium quality: Dune floor mats are awarded the world-renowned Oeko-Tex Standard 100 and manufactured according to ISO 140001:2015. Care tips: The Dune dirt trapper mats can be easily shaken or knocked off to remove coarse and dry dirt. Likewise, the mat can be cleaned of stronger dirt with a garden hose and water (not a pressure washer). Alternatively, it can be washed at max. 40 °C in the washing machine. Use mild detergent and spin the mat on a low setting. Then lay the mat flat to dry. Wash the mat once a year to maintain the rubber and to avoid dark abrasion on the surface.
