Answer 1

The dust that you’re seeing is also probably not absorbed, but in reality is the foam of the bus seat itself breaking down and flaking away. Bus seats get a tremendous amount of usage, and if that many butts sat on your office chair or sofa and got on and off the amount of times that people get on and off bus seats, you’d see the same kind of breakdown.
