Nice leather office chair?

I am looking for an office chair that is leather, and preferably a heavy duty chair. I am only 150 pounds but I am starting a work from home job and I really want a chair that is solid, comfortable, very nice leather. I have used a couple of heavy duty chairs at a couple offices I have been at that were meant for larger individuals, and I honestly enjoy them very much. They are big, solid, and comfortable.

Where do people order office chairs? I mean nice office chairs. Even in court rooms for example they have nice office chairs not those mesh or fake leather that falls apart after half a year
