Daily anti-stress relaxation The fabric’s antistatic properties help disperse the electrostatic charges accumulated by the body throughout the day. This promotes deep relaxation, helping to combat stress and tension for a more serene, rejuvenating sleep. Carbon Relax Technology At the heart of the product lies Carbon Relax, the innovation that generates heat without the use of electric cables, by integrating carbon fibre yarns directly into the fabric weave. The result? A product that is soft, flexible, and durable — just like a traditional fabric — but with something more: the ability to transform sleep into a true ritual of well-being. Sonno Sereno Topper: your ally for deep, safe, and sustainable sleep. Choose it to improve the quality of your sleep — and your life.
