Each Bio-Mat ™ Amethyst uses Japanese Kurare Carbon ceramic (Patent 1386560), that reduces electrical consumption 60% or more as compared to other electric mattresses. Bio-Mat™ mx Amethyst also has a special function that emits Negative Ions and transforms positive Ions to negative Ions in the human body which provides strength and energy to the human body and relieves pain. The Kurare's Super Fiber Materials generate Far Infrared Rays (8-12 micron) that the human body can easily absorb. A special layer of double Fiberglass completely cuts off harmful Water Vein Waves. The Bio-Mat ™ Amethyst comes with an advanced IC chip and soft-touch control system, which has many convenient functions.
