1. A headrest assembly for a seat, comprising:
a headrest cushion;
a neck support cushion;
one or more extension members coupling the neck support cushion to the headrest cushion, wherein the one or more extension members are configured to telescopically transition between a retracted configuration and an extended configuration, wherein in the retracted configuration the neck support cushion is adjacent to the headrest cushion and a first dimension is defined along a central longitudinal axis of the one or more extension members, wherein in the extended configuration the neck support cushion is cantilevered from the headrest cushion and a second dimension is defined along the central longitudinal axis of the one or more extension members, wherein the first dimension is less than the second dimension, wherein the one or more extension members are configured to releasably lock to secure the neck support cushion in a fixed position relative to the headrest cushion at least while in the extended configuration,
wherein the neck support cushion is configured to support a neck of an occupant of the seat while in the fixed position;
a headrest cushion hinge pivotally coupling a proximal end of each of the one or more extension members to the headrest cushion, wherein the headrest cushion hinge is releasably lockable at more than one angle defined between the one or more extension members and the headrest cushion; and
a neck support cushion hinge pivotally coupling a distal end of each of the one or more extension members to the neck support cushion, wherein the neck support cushion hinge is releasably lockable at more than one angle defined between the one or more extension members and the neck support cushion.
