A suspension system for the spring or damped suspension of a massive body relative to a substructure. The suspension system comprises a spring/damper arrangement disposed between the massive body and the substructure, which comprises at least one damper element and/or at least one spring element for damping shock and/or vibration, and includes a Watt linkage arrangement with at least one Watt linkage. At least one spring element and/or at least one damper element is arranged in the area of a Watt link between the Watt link and the bearing seat associated with the Watt link.
