I have an 8" riser for seating and a 20" stage. We used the same carpet for the stage that we used for the rest of the room. It's a Shaw low rise pattern. It "upholstered" quite nicely - that's the term the carpet guys used to describe the work to cover the stage and riser....
I'd imagine that the more shag-like the carpet, the more likely it will show the backing when you bend it. Mine is "loop", but I can get you the specific name and type if you like.
