The bag offers plenty of space for little things that are important during the trip for my mouse. Drinks are also good to stow away. In our 5-seater the attachment is quite possible. A loop on the back pocket is attached to the middle chord. Unfortunately keep the burs not particularly good. Furthermore, I have in my little car no middle chord (have a 4-seater). Thus, I can not fix in the middle and unfortunately the distance is then to pocket too big if you do it firmly with the other backseat belt pocket. Here comes my little one (2 years) not go. For larger children which should however not be a problem.
