A portable headrest apparatus engages a top of a chair with a U-shaped bracket sized for clamping onto the chair top. The bracket provides a quick-release clamp holding a telescoping rod extending downwardly. An adjustable elbow joint at a downwardly terminal end of the rod enabled rotation of a support arm extending to a head rest mounting plate which is pivotally engaged with the support arm. A head rest cushion is removably attached to the head rest mounting plate which is thus able to be positioned for comfortably resting one's head in almost any position desired.
