Bonded leather "Happy Leather" is made by shredding leather scraps and leather fiber, then mixing it with bonding materials. The mixture is next extruded onto a fiber cloth, or paper backing, and the surface is usually embossed with a leather-like texture or grain.ower-quality materials may suffer flaking of the surface material in as little as a few years, while better varieties are considered very durable and retain their pattern and color even during commercial use. Because the composition of bonded leathers and related products varies considerably (and is sometimes a trade secret), it may be difficult to predict how a given product will perform over the course of time. There is a wide range of bonded leathers and related products; some better-quality bonded leathers are claimed to be superior in durability over low-quality genuine leather. The use of terms like "leather", "genuine leather" or "100% leather" in relation to bicast treatment is considered a misrepresentation. www.stlouisleatherrepair Com
