This can cause the lumbar spine to bend downwards, the vertebrae remain in an unnatural position and strain muscles and ligaments. In this position, the key to achieving sleep comfort is to restore the natural posture of the spine. This can be achieved by placing a lumbar support pillow underneath to lift the lumbar spine and align it with the rest of the spine. On your back: if you sleep on your back, gravity pulls the lumbar spine (lower part) towards the sleeping surface and flattens the natural \"S\" curve of the spine. This poor sleeping position can enlarge the lumbar spine and cause discomfort. Place the lumbar support pillow under the lumbar spine (normally the knee) to restore the natural contours of the spine.
