The present invention is a seat bottom suspension system adapted to provide a varying spring constant. An embodiment includes a first plurality of generally flat elongated biasing members in communication with an axle adapted to translate in a direction generally parallel with the longitudinal axis of the biasing members. An embodiment may include a second set of flat elongated biasing members set at a lower height than the first plurality of flat elongated biasing members to provide a progressive increase in the spring constant as the down force seen on the seat increases.
