The headrest assemblies include a headrest cushion, a neck support cushion, and one or more extension members coupling the neck support cushion to the headrest cushion. The extension member(s) are configured to be transitioned between a retracted configuration in which the neck support cushion is adjacent to the headrest cushion and a first dimension is defined along a central longitudinal axis of the extension member(s), and an extended configuration in which the neck support cushion is cantilevered from the headrest cushion and a second dimension is defined along the central longitudinal axis of the extension member(s) that is greater than the first dimension. The extension member(s) are configured to releasably lock to secure the neck support cushion in a fixed position at least while in the extended configuration.
