CSAS is an abbreviation of Complex Shock Absorption Structure. This complex material combines Solid Gel with Rubberized Gel Foam to become a complex structure that will offset the stresses, transmit the forces to Wriggled Force, Lateral Force, and Remnant Force, and effectively achieve the perfect effect of shock absorption. Furthermore, CSAS can be widely applied in many industries, such as cushion for saddlery, kitchen mat, boxing protector, motorcycle seating, and so on.
