>Is the furniture I sit in every day made with harmful substances?

If I made you a chair out of wood and finished it with pure linseed oil, do you promise not to complain that it needs repainting regularly? If I make you a cushion out of horse hair and canvas, do you promise not to complain that it is uncomfortable and not flame retardant? Will you be ok that you can't wipe off stains like you could with your old one?

The convenience of modern materials is what drives this, as much as the profit motive
