Hmmm... could use geometry editor to create the seat of the chair as a separate surface and then apply a shader to that... Guess what I've been learning recently?

Well, I obviously don't understand it as well as I thought I did. I did turn the seat into a separate surface, but then couldn't do anything with it. So, instead, I went for brute force. This is the chair with a light grey velvet shader applied. Not terrific but it would make the models stand out. I'll just se what other chairs I have.
