The Yogawrap with non-slip straps is ideal for office chairs & leather chairs to offer back support. It provides relief for back pain & sciatic pain. This model is the same as the original Yogawrap but comes with the added non-slip straps. Yogawrap Spine Support stimulates core muscle activity. This is because it takes muscle activity to hold an upright posture. The Yogawrap Spine Support puts the upper portion of the body in the erect position, causing muscle activity.
