Dear all, We would just like to offer our experience. PVC is actually 100% synthetic leather. PU is actually leather bonded with plastics and in the past that is true PU is of better quality than PVC. However, there are PU and PVC of different grades today, especially with more and more manufacturers of PVC, and PU, with different constitutes, ingredients and make, bringing out different quality. As such, some PVC might be better than PU. Similarly for 100% genuine leather, there can be poor treatment process which results in poor leather. 100% genuine leather, generally last longer, but if it is not taken care properly, it might even have a shorter lifespan as PVC or PU.
