You might not think of it.  But sometimes when you are traveling in and out of airport, bus stations, hotels, etc. - you might want to find a place to sit.  Often times, you may not want to sit on a dirty bench or filthy bus station chair.  Or heck, you might not even find a seat in a crowded airport.  Waiting in long lines can tire you, so these types of luggage might just be the best solution.  

Check out these two cool travel bags.
