747 miles in the truck and no pain.
I bought the cushion to give me support while driving my Toyota Tacoma from Cleveland,  OHio to Rochester, Minnesota( a good 11 1/2 hour trip.  It worked like a charm...no pain at all.  I had used pillows for support before but they didn't work that well.  The only problem was that the thickness of the cushion made it a little difficult to get into the seat(my head would hit the roof but once in place no problem.)  I look forwards to using the cushion on aircraft and while traveling on buses in South America.  I only hope that the folks at the TSA won't think its dangerous because of its gel composition.  I have shown theis product to my friends and family.
