A seating system includes a seat, with structures for supporting a user thereon, and actuators. Each actuator includes a deformable shell with an enclosed internal cavity containing a fluid dielectric contained, a pair of electrodes disposed on opposing sides of the deformable shell. The actuators are integrated into the structures and configured for providing at least one function, such as haptic feedback, seat adjustment, alert notification, vibratory signal, user input receiving, and massage function. A portion of the plurality of actuators may be enclosed within an encapsulating shell to form an encapsulated sheet of actuators. Each actuator may be a part of a button-on-demand system, wherein the actuator is normally in a collapsed position such that a user-facing surface of the encapsulating shell is substantially flat and, when activated by a user, the actuator is configured to expand such that the encapsulating shell is raised to form a button.
