The picture I linked is of a buckwheat pillow. Had no idea they were a thing before today.
What about silk or bamboo pillow cases?
I’ve only ever really used cotton pillow cases and cotton stuffed pillows. I recently upgraded to a foam pillow that I’m enjoying.
Buckwheat pillow with a thick flannel cover. Belly sleeper and my pillow travels everywhere I do.
Buckwheat, in my opinion, takes a good 6 months for it to be properly broken in, but once it is I have a good couple of years of amazing sleep.
