PU leather is JUNK and ultimately I would NEVER spend $350-$500 on a chair using PU Leather or Vinyl as a material. Even if it's the best PU leather known to man the fact is that PU leather is not as comfortable, durable or cleanable as a good protected leather.
Polyurethane Upholstery PU is made by coating a backing fabric such as cotton, polyester or shredded leather with a flexible polymer and then treating it to look more like animal hide. Polyurethane upholstery is the most realistic imitation of genuine leather, with respect to hand, surface feel, and overall appearance.
