Leather definitely has nothing to do with this issue. Its simply the SHAPE of the seat. With the seat height in a normal position the slope of the seat base is so great that the base of your spine takes a high load. This coupled with zero support for your lumbar is the issue. You shouldnt need to get the optional lumbar support adjustment to HAVE lumbar support, just to adjust it. Then there is next to no lateral support either, its like a park bench - there is nothing to lean on around a corner - you have to use your own core muscles all the time. Hardly makes for anything resembling comfort.
