Do they work well in pickups?
Try a millet hull or buckwheat pillow. They are great!
Have bought a couple more for the bunkhouse in the calving barn and the couch when I am forced there.
I have a hard time believing gst is the type to be relinquished to the couch by an unhappy bunk mate. Maybe he's a gassy sleeper.
Ditto on this, in Japan where I first ran across one they were called "sobakawa" pillows, Japanese for buckwheat. Awesome pillows for hot sleepers.
