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.
Depends on what you mean by last.
I still have one feather pillow from about ten years ago. It’s still a pillow, but it’s gotten lumpy, less full, and it’s really only still around because of a strange nostalgia. It got to the point where it slept poorly at about a year. To be fair, it wasn’t the “best” possible.
Buckwheat, I got a little longer before it lost enough filling to break down that it wasn’t viable, about two years before I was just done with it being progressively flatter.
you can also just add more buckwheat if it gets too flat too. although fwiw I bought one a couple years ago and took out a bit to make it flatter initially, and haven’t needed to add it back yet
