These rugs are made from 50% polyester and 50% velour, which is soft to the touch, making them very easy to clean, even on the most stubborn stains. Non-slip rug, machine washable at 30°C. Made from polyester, non-slip, latex backing, 9mm thick, 1000 g (±7%)/m2 As our rugs are machine-made, there may be a variation of plus or minus 3cm. This is not a manufacturing defect, which the customer accepts and acknowledges. Because it has been rolled up, this mat may be a little lumpy when unrolled. This will disappear automatically after a short time. Rolling in the opposite direction may help. Suitable for underfloor heating. In order to minimise our shipping costs, your rug will be shipped folded. This does not damage the rug in any way as it is machine washable.
