SeatDreamzzz is the world's most-versatile sleeping mask that prevents the classic head-bob many of us are familiar with while traveling. By using the additional airline strap a user can fasten their head to the independent headrest, making it easy to fall asleep while sitting upright. Upon arrival at your final destination, the airline strap can be removed and and used while sleeping horizontally.
