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.
I’ve been using my homemade buckwheat pillow for about 5 years now, and it’s still doing great. The hulls are surely degrading, but even if it’s different than it was, it’s still very comfortable as is.
