Abstract
A seat suspension system controller is described for controlling both the latching and unlatching of a seat and seat height adjustment when the seat is unlatched. In one embodiment, the seat suspension controller is a valve actuated by a common lever to control a latch to unlatch and latch the seat and also to control seat height adjustment when the seat is unlatched. The lever may be oriented to unlatch the seat and raise the seat height when the lever is raised and to unlatch the seat and lower the seat height when the lever is lowered.
