Answer 1

when chairs/sofas filled with foam are compressed by being sit upon, the air inside the foam escapes and helps remove or at least loosen the surface dust so it more easily escapes into the air or is trensfered to the person. An un-padded but fabric covered seat wouldn’t have that air flow.
