My wife and I are going on a cross country trip from Guelph, Ontario to Fort Collins, Colorado to Vancouver, back to Guelph, Ontario. My wife's neck and back act up a bit during long car rides. I've read from some earlier posts that frequent stops and stretching help out a lot. But I was wondering if there are any back and neck support cushion things that can help me wife out. We are going to use a 2007 Aveo for the trips, so the seats are so so. Any recommendations would be great. Thanks
