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.
Maybe I should give buckwheat a try, or shredded latex. I’m probably due for a change but lately I haven’t been able to afford any sleep disruption.
