Now I have a problem with my hip if I sit too long in the car, and wife has a problem with her back, I would hope a $20 solution like this would help as it has helped us drive on pain free. I also find the slight pressure of the seat belt causes severe discomfort on a long trip so I us a clip or a coin to maintain a little slack in the seat belt. If I were to hazard a guess it is the front of the seat is reducing circulation, and this hopefully will help you as it has helped us.
