Tourmaline has DC static electricity, because tourmaline is a polar crystal, which naturally and permanently produces a "positive electrode" at one end and a "negative electrode" at the other end.
Moreover, the positive electrode and the negative electrode are often in an unstable state, and this instability and imbalance produce a "potential", because with the potential, electrons constantly flow from the negative electrode to the positive electrode. This electron flow is the essence of tourmaline electrostatic charge.
Tomalin is an international outstanding rare gem, which is rich in permanent electrodes and 10 kinds of important mineral elements. It has seven health-care functions: relaxing bioelectricity in freedom; Healthy negative ions; Rich in minerals and trace elements; Promote blood circulation; Form Toma energy field and enhance cell activity; Effectively block the water pulse wave; Bacteriostasis and deodorization.

History of mattress development:
1 year, 188 1 year, in a small town outside Houston, Texas, USA, Daniel Haynes, a cotton baler craftsman, began to make a cotton mattress.
2. 1900, Maximus, bagged spring mattress;
3. At the beginning of the twentieth century, Danlov, rubber foam pad;
4. 1932, Mario Berezi in Italy used polyurethane foam as the floor mat;
5. During the Second World War, German Louis Kalanyi also designed an oval mattress, which was divided into soft, medium and hard parts according to the body pressure of different parts of the mattress, so as to keep the human bones in the best condition.
6. There is also an "active response spring system" abroad, which changes the usual spring structure and makes people more comfortable and elastic. Some spring mattresses are also combined with polyester foam, and the hardness can be selected by people.
