comfortably off
Having enough financial means or assets to be able to live in comfort. Jim is now quite comfortably off after marrying Suzanne, whose father is a billionaire oil tycoon.
not sit comfortably (with one)
To not be agreeable to one's values or sensibilities. The idea that some children have to go hungry in this country just doesn't sit comfortably with me. Some aspects of my proposal didn't sit comfortably with them, but I assured them that things could be changed to accommodate their preferences.
