A seat suspension system for a vehicle and including a seat attached to a seat support. The seat support is supported for movement through links on a frame attached to the vehicle. The seat suspension system includes stabilizing means in the form of a pair of coil springs having one end attached to the frame and the other end attached to the seat support with the ends of the springs limited for rotational movement only so that the effective spring force per increment of seat displacement increases non-linearly relative to the displacement of the seat support. The stabilizing means further includes a pair of shock absorbers which are positioned between the frame and the seat support and are attached in a manner that the shock absorbers will be substantially fully retracted in the normal ride position of an operator.
