A method is provided for improving posture and relieving back pain of a person in a supine position. The invention includes the steps of pressing a convex pillow against the region of the ilia, sacrum, and fifth lumbar vertebra to produce a substantial sacral base angle and to fully oppose any moment tending to cause rotational shifting of the pelvis, and supporting the thighs and calves in an elevated position such that the thighs extend upwardly at an angle of from about 53 DEG to 63 DEG from horizontal, and the calves extend at an angle of from about 0 DEG to 20 DEG downwardly from horizontal. The method normally also includes simultaneously resiliently supporting the back of the neck in an elevated position while permitting the cervical vertebrae to maintain their normal, physiologic curvature, in supporting the head of the person in an elevated position while maintaining the cervical vertebrae and the occiput in an unflexed, physiologic position.
