The perfect balance for the human body is determined by the time and the quality of our rest; an active phase of daily life where one can feel rejuvenate to better face the new day. Knowing what factors may affect the quality of our rest, such as body structure, age, stress, can promote it and protect it, due to the important role it plays from the health standpoint. From the physiological point of view, to sleep well the human body requires a harmonious support, which maintains the correct posture respecting the natural curvature of the spine. Restoring the nervous system is guaranteed by a restful sleep. To be restful, sleep should be stable and uninterrupted, so sleeping through the night is not necessarily a sign of quality rest.

A study carried out in Germany by the University of Göttingen, has determined that the number one enemy of uninterrupted sleep is the traditional mattress, where a person turns up to 70 times a night in order to avoid excessive pressure on the body. On the other hand, sleeping on a polyurethane mattress, which adapts perfectly to the shape of the human body, ensures an optimum weight distribution and lessens compression to achieve correct blood circulation, and consequently one turns over only up to 17 times a night. In this regard VEFER, a company that has always worked on innovative applications of polyurethane, has developed a series of products that allow the foam to take the shape of the body that must be supported.
