I'd love one of these wingback armchairs to sleep in—but I'd settle for more widespread use of the circa-2000 British Airways economy class seats with their three-part headrest, the outermost parts of which would fold down and forwards to create a very effective side headrest: http://benjaminjtravel.com/wp-content/uploads/2017/05/Trip-Report-British-Airways-Economy-Class-Boston-to-London-Heathrow-LHR-7.jpg http://benjaminjtravel.com/wp-content/uploads/2017/05/Trip-R... Their newer planes (and those on many airlines) have headrests that fold with a vertical hinge, but these invariably cause my head to tip forward when I fall asleep, waking me up again (if the hinge is even stiff enough not to just fold flat again when I lean against it).
