A vehicle seat provided with an active suspension, comprising: a resiliently mounted vibration-isolating frame ( 2 ), a seat mechanism ( 6 a, 6 b, 8 a, 8 b , 10, 13 ), which can be adjusted by means of at least two actuators ( 4 a , 4 b) and is articulated on the vibration-isolating frame ( 2 ), at least two acceleration sensors ( 11, 12 ), of which the first acceleration sensor is arranged at a spring supporting point in the vicinity of a first joint axis, and the second acceleration sensor is arranged at a spring supporting point in the vicinity of a second joint axis, and at least two final control elements (S 1 , S 2 ) and power and control electronics (R 1 , R 2 , FFC, E, CU) with which the signals of the acceleration sensors are processed and converted into desired adjusting forces (F* 1 , F* 2 ), which serve as control commands for the final control elements (S 1 , S 2 ) for operating the actuators ( 4 a, 4 b), so that the vibration-isolating frame ( 2 ) can be adjusted by means of the two actuators ( 4 a, 4 b) in two degrees of freedom of motion, and the forces which are introduced into the seat from the console of the vehicle chassis are compensated by means of the power and control electronics (R 1 , R 2 , FFC, E, CU) in two degrees of freedom of motion.
