Up with your back!You can determine how good a mattress is considering how much it respects and loves your back, favouring the correct position of the spine during the sleep. The maximum relax and wellbeing of the body can be obtained when neck, shoulders, back and legs are sustained correctly. The spine is in the correct position when it forms a straight line, without bends, from the neck to the legs. All this canbe possible only according to ergonomic criteria and with the use of raw materials of first quality that don’t lose elasticity and form with the passing of the time.
