Simpson Xplorer Jeep® seats are made using CNC bent tubing, nylon open weave mesh liners which allow for the dissipation of energy as well as to reduce moisture buildup and 3 different densities of antimicrobial foam to reduce mildew but more importantly reduce body heat and improve comfort. The Xplorer Jeep seats are designed to fit CJ, YJ as a direct bolt in replacement and adapters are available for the TJ and JK. The standard base rail pattern of 12"x14" on center allows for the use in most street applications.
