Leather has a completely unique character. Firstly, each animal and therefore each hide is different and unique in appearance. Additionally, it matures with age and so develops patina. Even the natural aniline leather from Leder Reinhardt that we use for our FRIDAY, MORPH LOUNGE armchair and for some chairs and upholstered furnishings, has visible signs of life. Even when it is coloured with water-soluble dyes, its grain pattern is clearly and completely visible. There are no colour pigments to be found in the leather, which is why all natural variations in the structure and colour are visible. As with all Leder Reinhardt products, aniline leather is also environmentally friendly and was manufactured without the addition of azo dyes in accordance with the German Chemicals Prohibition Ordinance.
