Vehicle seat assemblies including support structures having at least two supports parts coupled at an articulating joint and a pneumatic actuator system including at least one pneumatic chamber inflated and deflated to articulate the articulating joint to move one support part relative to the other or to synchronize movement of two support parts. Support structures can include a backrest coupled to a seat bottom or leg rest coupled to a seat bottom, wherein articulation of the joint causes movement of the backrest or leg rest along a non-hinged trajectory to change a sitting position of the support structure, change seat orientation, and generally improve seat comfort.
