I travel frequently and have tried many different things to be comfortable during 12+ hours of travel. This is the best I’ve used so far. It keeps my head straight, and I can take a nap very comfortably. I recommend using it with a U-shaped pillow to provide extra neck support. With this combo, I was able to sleep comfortably for hours.One thing to consider: if the person is shorter and their head doesn’t reach the height of the airplane seat headrest, this might not fit. Absolutely not for kids.
