BetterBack® Seat Support
Product Review (submitted on July 3, 2012):
I have this better back seat for 10 years.. I use it in my car and when I travel on planes.. Its a lifesaver.. I also need it as a booster seat, but it allows my back to adjust to sitting properly which makes such a difference in my long or short trips.
I keep taking it from my car to my husbands car which at this point is sensesless and I am purchasing a new one so that I have them in both cars.
I highly recommend this to anyone with a back...LOL it is a comfort at a show, or wherever or whenever you are sitting for a long period of time.
It may be a bit cumbersome to carry, but worth the schlep.
