A powered wheelchair includes a seat assembly configured to support an individual, a curved legrest assembly pivotally connected to the seat assembly, and an adjustment assembly including an actuator operatively connected to the central column through a piston slidably secured within a sleeve. The adjustment assembly is secured underneath the seat assembly. The powered wheelchair may also include an extension bracket that allows legrests and a central column of the curved legrest assembly to be separately and independently adjusted with respect to one another.
