A retractable headrest assembly for a seat includes a headrest assembly mounted on a top portion of a seatback for pivotal movement between use and retracted positions about a first axis, and a retracting mechanism for toggling the headrest assembly to either of the use and retracted positions. The retracting mechanism includes a first shaft member defining the first axis and coupled with a seatback frame, embedded in the seatback, and a biasing element for urging the headrest assembly rearwardly about the first axis.
