An apparatus and method for adjusting the height of a vehicle head restraint includes a top cover, latch assembly, and bottom cover. The top cover is connected to the head restraint. A latch assembly is moveable in a lateral direction relative to a latch post, and a bottom cover connects to the top cover, sandwiching the latch assembly between the top and bottom covers. When the button portion of the latch assembly is actuated, the latch assembly unlatches from the latch post, allowing the height of the head restraint to be adjusted. By directly connecting to the underside of the head restraint, the apparatus is further operative to close out the bottom closeout opening on the underside of the head restraint and provide an aesthetically pleasing finish.
