Review on High-Quality Tablet Mount for Car Headrest - Multi-Passenger Backseat Holder Stand Compatible with Tablets: Apple iPad PRO Air Mini, Samsung Tab A E S4 - Anti-Vibration Swivel Cradle (7-15 inch displays) by Robert Tirona

Going on a trip and yes you need to keep the kids entertained. We used to have the problem that two children with two cell phones disturbed the sound. So, with this mount, we now have a total screen of 12.9 inches! So far it is fairly stable in the air, and removing the panel from the front row is not difficult. The only downside is that the screws that attach it to the headrest bars are ridiculously thin, I think it's an M4 screw. I wish they had used stronger screws.
