The kitchen chair has a pad with light green covering that Spouse frequently soaks because his Depends get flooded and he doesn't change them often enough to allow them to do their job. I'm planning to cover the pad with plastic to save laundering the whole pad each time and can sew a new cover on it. If he sees the stains, he's more likely to realize how bad the problem is. Now and then he notices when the pad gets soaked (from its appearance only, because wearing wet pants doesn't seem to bother him) and it seems to spark a Depends change.
