Abstract: The headrest of an upholstered seating unit is hingedly supported by a spring which biases the headrest to a substantially vertical raised position. The spring prevents the headrest from moving from its raised position when an occupant's head rests against it, but greater forces will bend the spring and move the headrest to a generally horizontal lowered position. The illustrated spring is a pretensioned vertical helical spring which has its lower end mounted forwardly of an upper portion of the furniture frame. The headrest can be moved to its lowered position by a cable/conduit associated with a pair of relatively movable parts of the furniture unit.
