A suspension device for suspending a mass relative to a substructure. The suspension device comprises a spring/damper arrangement which is disposed between the mass and the substructure and dampens vibrations, and comprises at least one Watt's linkage. At least one of the pivot points of the Watt's linkage is movably connected to the mass and the substructure. The relative position between the pivot point, the mass and the substructure can be adjusted by at least one substantially linearly acting actuator. The suspension device is robust and suitable for determining the vertical degree of freedom of movement of a truck driver's cab, and for damping or preventing undesired movement of the driver's cab. At the same time, undesired rolling or tilting motion of the driver's cab can be actively controlled or prevented by using the actuators.
