MagniStretch mattresses are designed to decompress your spine, reducing muscle contractions and relieving back and neck pain caused by bad postural habits. The 2 sets of inclined foam sections move in opposite directions in response to your body weight, creating subtle traction on your spine and increasing the space between the vertebrae. MagniStretch uses a technological patent created in collaboration with the Department of Mechanical Engineering of the University of Zaraoza, through an articulated program of ergonomic tests, and it is certified by ACA – AMERICAN CHIROPRACTIC ASSOCIATION – the leading national association in the USA – for the beneficial effect of lengthening and relaxing the spine in the mattress.
