Self-Inflating Back Rest - Rectangle
Product Review (submitted on January 4, 2011):
Inflates and deflates easily, just open the valve to inflate. To deflate open the valve and roll it up then close the valve.
Easily adjustable, just close the valve when it's big enough.
Rolls up and fits in briefcases.
Works great on airline seats, I am 6'3" and the airline headrests hit me in the shoulders making them very uncomfortable on long trips. With this I just wip it out, let it inflate and have instant lumbar. Then I can make adjustments in flight as needed.
