We are getting ready to travel again. The last time we did a short road trip (2 1/2 hours), I could barely get myself out of the Suburban my knees and hips hurt so bad. I realized the seat do not fit me very well at all and really aggravate my arthritis. When I bought the fabric for dirt bag mattress, I picked up an extra piece that was going to be shopping bags.
Car pillows were much more needed.
I put these together tonight. There are actually too. I can see much more comfort in my life that long ride to the mountain.
