Abstract
A spring support assembly for a bicycle seat, having a lower cylindrical post, an upper post concentrically disposed within the lower post and vertically slidable within it, the two posts together providing an enclosed spring chamber, a gas spring disposed in the spring chamber, the gas spring being pre-loaded to prevent reaction to a force of less than a predetermined magnitude, a metallic compression spring surrounding the gas spring in a concentric relation, and both spring devices supporting the upper post at all times so that all phases of the spring reaction occur as a composite function of the two spring devices.
