Many sofas are upholstered with full-grain or top-grain leather. Both materials are quality natural leathers, but there are distinctions between the two. Full-grain leather is left in its natural state revealing unique markings of the hide. Further, it has a durable and breathable surface that will develop a patina as it ages. Top-grain leather has been buffed and sanded to remove imperfections, blemishes and uneven coloring to provide the cushions with a uniform look. Leather sofas can also be full-aniline dyed, which means they are dyed only with soluble materials that protect the hide’s characteristics without concealing or altering them. Leather furniture is a strong choice for homes with a classic look.
