I like a medium pillow that lets my head sink in a little bit so my neck isn't cranked at an angle but not to the point where it sinks in completely. You can also scrunch it a little bit. Also love that it's queen size, as most queen sheet sets for come with queen pillow cases, not standard. I am surprised it worked out, very happy with it.
