Going to buy a buckwheat pillow, I think. Or more specifically, 10kg of buckwheat hulls and a few zip-closure pillow cases because that works out cheaper (and more flexible).
It's clear that firm mattresses and even firmer pillows are my thing. In fact, I need to find a way to stiffen up this memory foam mattress topper — the mattress underneath is so horrendously soft that the memory foam isn't as supportive as it should be.
I am probably amongst the few though. My best nights have been on tatami.
