Creature comforts are the best. Make no mistake I am not the now failed pillow guy but I did invent 2 versions of a refridgerated pillow. They work too well to be safe or are not silent. However the most available organic solution is a feather or down pillow that is washed and not dried completely. It should be plump and not wet to the touch but retain a moisture level that another 30 minutes in the drier would remove. That way the pillow is cool for about a minute or less and then can be turned over to feel cool again...repeat until sleep.
