i have never looked into portable dvd players, but just returning from holiday i have decided to get one for my boy (everyone had them / tablets on the plane)
do all portable dvd players fold open flat so they are flat against the chair in a car? (i dont want the disk tray bit sticking out in case it causes injury in a crash, but i want it so we can also take on a plane and it opens up and can be sat on the tray..

what should i be searching for? I am looking to use my CEX trade in vouchers but they dont have pictures with any of the players online...
