Arkon's headrest tablet mount is a road trip essential. This headrest mount is best suited for tablet viewing by one back seat passenger. You can attach it to the driver's or passenger's side seat if your car has the 2-post headrest configuration. It includes Arkon's Slim-Grip Universal Tablet Holder and the 2-post car seat headrest mount with adjustable arm. The Slim-Grip tablet holder fits tablets 7 to 18. 4 inches in screen size. The holder features a spring-loaded design that makes it easy to insert or remove the tablet by pushing down on the lower legs of the holder with one hand. Included with the holder are 10 support legs (4 short, 2 medium and 4 long versions). Choose the 4 legs that provide the best fit for your tablet. These insert at the top and bottom of the holder and can be easily adjusted in order to keep any side buttons and ports unobstructed. For most large tablets, the best mount holder configuration is to attach 2 short support legs on top and the 2 long support legs on the bottom of the holder. For smaller tablets, use all 4 short support legs on the holder. For larger tablets including iPad Pro, use all 4 long legs. For vertical viewing, adjust the 360-degree swivel.
