Leatherette is a form of artificial leather, usually made by covering a fabric base with plastic. The fabric can be made of a natural or a synthetic fibre which is then covered with a soft PVC layer. Leatherette bound books and 20th century cameras are good examples of leatherette.
Best Answer: PU leather is leather from the inner hide of the animal (usually a cow) because it's not the outer layer it has to be waterproofed with a polymer. So it is a real leather jacket, but like leather from a sun-burned cow that's peeled and you got the next layer down. On top of the PU leather is a finishing surface to give an external aspect like upper-layer leather. The inner layer gives the strength and suppleness, the outer layer gives the finish. It's the same leather that's used in most mid-range leather furniture. Hope that helps.
