Carpets are soft products and flattening of the pile will occur as a result of usage. Flattening may change the shade of the carpet (shading) and this may be permanent (pile reversal). This may appear to be random but this is not a fault. Areas of high foot traffic are especially prone to such changes in appearance. The side of the pile may appear to be a slightly different colour to the ends. Changes in direction or angle of the pile may change the shade of the carpet and this may appear patchy. Such changes do not affect the durability of the carpet and therefore we cannot be held responsible for any issues relating to pile damage.
