Now, travel pillows are totally different from the ones you use to sleep in your house at night and you will be pleased to discover that they really do make your trip much more pleasant. What's the difference? There is really a world of difference in a travel pillow and the regular ordinary pillows that you use.
If you are on a flight, you will find that you can adjust these pillows so that they can go across your body and you can thus tilt your head to the side. Whereas if you are in a car, you can very easily wrap these pillows around the seat belt of the car!
