Bonded leather, or reconstituted leather, is an artificial material composed of 80% to 100% leather fibers (often waste scraps from leather tanneries or leather workshops). It consists of collagen fibers obtained from macerated hide pieces bonded together with latex binders constructed into a fibrous mat to create a look and feel similar or sometimes identical to that of genuine leather but at a fraction of the cost. Depending on the quality a man-made pattern is usually discernible as a "grain-like" look.
Examples of products that are most commonly constructed with bonded leather are: bibles, diaries, art books, desk accessories, hymnals, bags, belts, chairs, and sofas.
There are manufacturers who call their chemical treated leather, bonded leather.
