I rather like my soft pillow and have a hard time imagining using a hard ceramic/stone pillow. But these ancient civilizations did it, some for thousands of years. Maybe there is something to it and it isn’t as uncomfortable as it seems?
Do note that in modern terms takamakuras at least are neck braces, they don’t support the head itself.
This is coherent with the complex and tight hairstyles of the time which would be impossible to do on your own, and difficult to redo every day even for nobility. So keeping hairdos protected would be important, something a soft western pillow would not achieve easily.
I believe that's how asian cultures used their hard pillows (also keeping the complicated / tight hair-does elevated to not ruin them during the night). It's certainly how I use my buckwheat (minus the hair-do).
