This technique is designed to keep the hips, pelvis, and spine in a more neutral alignment. It may suit side sleepers who experience lower back pressure or hip discomfort. However, a key limitation is that it is not a medical cure for chronic conditions, and its effectiveness depends heavily on an individual’s body proportions and mattress firmness.
