Koomus Universal Headrest Mount Holder Cradle for tablets, iPad, iPad mini, Samsung Galaxy Tab, Galaxy Note 2, Note 3, Microsoft Surface
I use this for my son.  I simply snap it in place on the headrest in front of his car seat and we are ready to go.  He watches his favorite movie, while I drive.  It comes in very handy for when I have to drag him along on errands.  The Koomus Universal Tablet Headrest Mount works great for both my ipad and my husbands Samsung.  It is very universal and strong device.
