The neck posture issue is simple. You want to support your head so your head and neck and spine stay straight. If you sleep on your side, a firm thick pillow helps. If you sleep on your back, a thinner pillow that you can tuck into a ball at each side of your ears so your head stays straight and does not roll to the side can be good. You do not want much head lift if you sleep on your back. That strains C-1 and C-2. Some of us get our best sleep in a cozy recliner.
