The SOFT Mat Full 7224 stands out because of its crushed natural tourmaline ceramic, amethyst, and jade gemstone composition. The smaller size of the gemstones creates a surface that conforms to the contours of your body, maximizing comfort with each use. The lack of PEMF and photon lights in this model is an advantage because having fewer layers makes it flexible enough to roll up and substantially decreases the weight. You should use the SOFT Mat Full 7224 on the floor or in your bed because of its size. It is ideal for receiving full body therapy sessions that facilitate maximum results. If you have sensitive skin or know you are looking for something comfortable then this is the mat for you. Avoid the firm surfaces of other gemstone mats, and maintain your wellness with maximized pleasure.
