I used to sleep on buckwheat pillows. I loved those pillows. For about the last 15 years, I have slept on memory foam pillows. I have a difficult time sleeping without them now. But they are not all created equal. I have tried several that were cumbersome, unpleasant and almost hard. I had a couple that were my favorites but I don't know who made them. I am always searching for one that is just right.
