So what is good sleeping posture? We strongly recommend sleeping on your back as its easiest to keep the spine neutral as you sleep.
Your mattress and pillow choices can also help your posture.

Select a firm mattress or an ensemble that does not sag. If necessary, place a board under your mattress. You can also place the mattress on the floor temporarily if necessary. If you've always slept on a soft surface, it may be initially painful to change to a harder surface. Try to do what's most comfortable for you.

The human neck curves slightly forward (to sustain the weight of the head when upright), and it is very important to maintain this curve when in a resting position. If the height of the pillow is too high or low when sleeping, your neck is bent abnormally out of alignment, causing muscle and joint strain. You can even wake with headaches.
Poor pillow support can also cause narrowing of the air pipe, resulting in obstructed breathing, and sometimes snoring, which can hinder sleep.
