Hi steelwindmachine,
A suitable pillow is an essential part of good alignment for the head and neck and upper body because the gap between the head and the mattress and the curve of the cervical spine needs to be supported just like all other parts of the spine. Like mattresses … there are certain “needs” that depend on body type and sleeping positions but with pillows more than mattresses, personal preferences play a more important role because the face is much more sensitive to textures, temperature, smells, and other more subjective “feel” based properties of a pillow. There is more about choosing pillows in the pillow thread here including a number of links to some additional forum posts and topics that discuss various pillows as well in post #3 in the topic.
Not surprisingly I think that MattressToGo’s suggestion is a great one and would be well worth trying. It may be worth considering a shredded latex pillow that is contoured such as this.
