The High-tech Profiled Foam is a polyurethane foam treated with 22 special products, including antibacterial and antifungal agents. The high relief of the profiled foam provides a relaxing self-massage similar to shiatsu, meaning its shape gives the sensation of hundreds of fingers massaging your body. The low relief facilitates the evaporation of perspiration, preventing the proliferation of fungi and bacteria due to its porous nature. It aids in good ventilation, allowing the body to breathe more during sleep, reducing perspiration and facilitating its evaporation, thereby contributing to better respiratory function and keeping the sleeping area sanitized and free of bacteria.
