The present invention is directed to a seat and seat suspension assembly comprising a seat mounted to a seat supporting platform and suspension mechanism, the platform and suspension mechanism being rotationally mounted to a base by a pedestal so that the platform, suspension mechanism and seat may rotate through 360 degrees. The pedestal comprises two swivel housings, the first swivel housing being mounted in fixed position on the base and the second swivel housing being rotationally mounted to the first and supporting the suspension mechanism, platform and seat. A suspension spring and damper are associated with the suspension mechanism to enhance the ride characteristics of the seat, with the damper being positioned inside the pedestal and having one end connected to the first swivel housing and the other end connected to the suspension mechanism.
