Hi Anna,
I LOVE my buckwheat pillow--but not for my head. Too noisy. That buckwheat is crunchy and rattles right in your ear all night. I use mine because I have lower back problems. I cradle it in my stomach at night when I lie on my side and it helps support my back. It's the most perfect pillow I've ever found for that purpose. It molds into the right shape and stays cool, even in the summer.
