Top Grain leather is considered as the second highest grade of leather, and is as strong and durable as full grain leather. It is split from the top layer of hide and sanded and refinished. Genuine leather is made from the remaining layers after the top layer has been removed. It has a suede surface that is refinished to appear of a higher grade. Top Grain leather is considered as the second highest grade of leather, and is as strong and durable as full grain leather.
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.
