I am a chiropractic doctor, and I can tell you this is an essential addition to your tools for dealing with low back (lumbar) and sacroiliac pain.<br />great for chair, coach and car to maintain lumbar curve, relieve pressure and allow joints to heal.<br />Add long sleeping pillow for nighttime lumbar support,muscle simulator to relieve spasm, SOT blocks to help alignment if you know how to use them, and a sacroiliac or lumbar belt support to get you through the difficult times.
