A headrest is provided for use with a chiropractic table and comprises a base plate and a strap for securing the base plate to the table. A support plate is hinged on one edge to one edge of the base plate so that the support plate is pivotal between an upper first position and a lower second position. A latch assembly retains the support plate in its upper first position but releases upon the application of a predetermined pressure on the support plate to permit the support plate to move to its lower second position.
