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.
Modern patent leather is finished with a mixture of acrylic and polyurethane which gives a longer lasting more scuff proof/crack proof finish. It is however common to come across fake patent leather which is some man made fabric with a similar 'plastic' finish to it.riginally patent leather was made from top grade real leather, highly polished with different types of oil and lacquers. Modern day patent leather is often coated with or mad â¦ e from plastic.
