For Back: Effective for any kind of lower back pain. Lie down on the flat surface (preferably floor) and put the pillow under the lower back (Lower Lumber and Upper Pelvic) region, where pain is being observed, for about 10-15 minutes. For Neck: Supports the natural curve of neck and provides gentle yet firm pressure at the base of the skull. Cylindrical Neck roll provides excellent neck support in Yoga postures and offers relief to tired or tense neck. Also helps reduce head and neck strain.
