Abstract
A wheelchair suspension system which includes two springs with at least one damper and a central movable component that attaches to a wheel on a wheelchair. The damper is positioned in the center of at least one of the two springs and resists sudden force acting against the wheelchair with the two springs, the central movable component moves either in an upward or downward direction when there is force acting on it from both the springs and damper or by the uneven terrain. The wheelchair suspension apparatus will create greater stability for the entire wheelchair and increase the comfort of the user.
