Abstract: A high tension coil spring structure for a bed mattress includes spring bodies and exposed wiring portions which absorb an external load. Diameter-increasing portions (A) are formed on at least one of upper and/or lower end wiring portions (14, 14?) of body wiring portions (12), and provide spaces in which upper and/or lower exposure start wiring portions (16-5, 16-5?) move upward and downward.
