This is the basic elastic and velcro. It works in any direction around your headrest and the tablet holding parts are detachable/adjustable. As long as the Velcro stays attached, your tablet will remain secure. The velcro pulls the hair on the back of the headrest and I'm not sure how much I trust the velcro that holds the tablet.
