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.
Yes. I can’t talk about buckwheat in particular but, considering your face goes on it, I consider a good pillow case more important than a good set of sheets.
