In what ways are couchsitters and divansitters different?

Couchsitters have more job opportunities minding the couches while their owners are away. Divansitters are more niche. Most people have couches nowadays

I've never heard of a divan-potato so I'd guess the divanlayer is a fair bit less likely to be a tuber.

Keeping your feet on the ground makes you MUCH less likely to fall asleep while sitting. I suspect the couch sitters are more alert.

Divan layers just have a certain elegance that couch sitters will never achieve.
