@Angie @cowgirl836 and any other vertically challenged people:
I have a dogbone style pillow that I use for both the car and airplanes because of where the headrest hits me. It's filled with microbeads and is light as a feather, doesn't get hot like those horseshoe pillows do, and has an elasticized strap that fits over the seat back to hold it in place. Both the cover and the pillow are machine washable; I dry the cover in the dryer, but I air dry the pillow.
I don't go any distance without it. It looks like this, but mine has a single adjustable elastic strap that goes from one end to the other instead of the two small end-straps pictured.
