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.
Surly there exists some artificial material that perfectly mimics the properties without degrading.
Yeah, plastic pellets!
Maybe ceramic pellets could work as well surly it would help both sides of the pillow be cold.
That reminds me of the cheap weighted blanket reviews I saw where people were complaining about them leaking beads after a while. I think it was glass then though.
I'd always prefer a biodegradable and renewable material that I have to replace every few years over an artificial one that'll be around forever in some form. Not everything needs to be made out of petroleum
Just cos something is around forever doesnt mean its bad. I mean rocks exist practically forever. If plastic didnt disrupt ur bodies chemistry then there really wouldnt be much problem letting it exist in the environment forever.
