Chiropractic Mattresses The position of your spine while you sleep is of the utmost importance to your health. When abnormal stress is placed on your spine, tension may be caused in adjoining ligaments and muscles. We have a range of mattresses that are developed by the Chiropractors’ Association of Australia and endorsed by either the Chiropractic and Osteopathic College of Australasia (COCA) or the International Chiropractors Association (ICA). Sleep plays an important role in our health and wellbeing so choosing the right mattress is absolutely essential.
