We use dyed top grain bovine leathers to cover our upholsteries. "Top grain" is the upper surface of a cowhide with its individual, natural appearance. Only hides from animals that are not too scarred can be used to produce this leather. Our leathers medium thickness is between 1,1-1,3 mm and they all have a beautifully pronounced natural grain. Inferior hides need to be ground down and artificially textured to hide the scars and marks. They are relatively thin (0,6-0,8mm) and their surface may show cracks after some time. To get best quality, we also use a tanning process that not only preserves the beauty but ensures high durability as well. Properly treated (i.e. not exposed to direct sunlight) our furnituire will last for decades.
A word about thickness: Thicker is not necessarily better! Whenever leather has to follow a certain shape, (like in most cases when making furniture) a thickness of 2mm does make no sense, but gives the whole piece a clumsy look. Whoever states using such i.e. on a corbusier armchair, probably does not know much about his products.
