applying a first rotation response and a first heave response to the seat with a first control strategy;
receiving a vehicle condition of the vehicle;
determining a second control strategy based at least partly on one or more of a driving condition and the vehicle condition; and
applying a second rotation response and a second heave response to the seat with the second control strategy;
wherein the first control strategy has a first maximum threshold for at least one of heave and rotation, and wherein the second control strategy has a second maximum threshold for the at least one of heave and rotation wherein the first maximum threshold is different from the second maximum threshold.
