A pil­low for trav­el­ing in an air­plane or car is one of the most pop­u­lar attrib­ut­es. No mat­ter how com­fort­able the chair is, it is not meant to be slept in. Some­times after a trip or flight, a per­son­’s day is just begin­ning, he does not have time to rest. For this rea­son, the issue of com­fort­able, full-fledged sleep while trav­el­ing remains rel­e­vant.
