Unlike ordinary commercial mattresses, which focus primarily on fabric design and merchandising, the Chiro-Matic Sleep System is designed and engineered exclusively to stringent professional Chiropractic specifications. The Chiro-Matic Sleep System properly supports the spinal area, and scientifically contours the body configuration. With the Chiro-Matic Sleep System, lower back muscles now receive a full night's supportive rest and are able to provide full support to the lower spine the next day. In addition, the Chiro-Matic exclusive, custom-crafted sleeping surface is designed to reduce body pressure points to give your full body a good night's rest. Because of our unique engineering, body muscles are rested and revitalized.
