Integrated in a user-optimized seat for OEMs, it utilizes a high-strength mechanical scissors-type suspension and adds improved height and weight adjustment as well as a fore/aft isolator. The MSG 285 suspension can be combined with the S 700 upper seat section, which is available in a number of versions, to assemble a complete modular seat. It corresponds to ISO 7096:2000 EM 3 to EM 9. A combined weight and height adjustment mechanism is included. The seat can be set for weights from 50 to 150 kg (operator plus additional equipment).
