Abstract: An adjustable seat pedestal that allows a user to adjust the height of the seat without sacrificing ride quality. The seat pedestal has a top carrier onto which a seat is mounted and a base that is mounted to the floor of a vehicle. A scissor linkage is employed to allow movement of the carrier toward the base when force is applied through the seat to the carrier when the vehicle hits bumps and forces the user downward. An air bag biases the top carrier upward away from the base. As the upper ends of the scissor linkage move closer together by being pushed upward, a sliding end of the scissor linkage is restrained from movement inward and therefore, limits the maximum height of the pedestal. The pressure in the air bag may be varied which will not change the height above the maximum, but will change the ride quality.
