Bonded leather, also called reconstituted leather, composition leather[1][2] or blended leather, is a term used for a manufactured upholstery material which contains animal hide. It is made as a layered structure of a fiber or paper backer covered with a layer of shredded leather fibers mixed with natural rubber or a polyurethane binder that is embossed with a leather-like texture.
It differs from bicast leather, which is made from solid leather pieces, usually from the split, which are given an artificial coating. Bonded leather may be made in a similar manner using casting paper.
