It is leather with a high gloss finish which is synthetic and usually polyurethane. There are various qualities, most are made from leather that is too marked or scarred to be used with a natural finish so is given either a corrected grain or patent finish. Pleather is where the coating makes up more than 50% of the thickness of the finished material and is usually the bottom split of a hide heavily coated to give it strength and a decent look. Can the layman/woman tell the difference or quality of a patent leather or the quality of the underlying leather? Basically No
