Well he's been in the 3rd row for years - first in a latched harnessed seat and when he outgrew the latches I just belted the harnessed seat in. He prefers his own little domain in the 3rd row next to the charger for his ipod, cupholders etc. DD is in the passenger side captain's chair and the other captains chair is stowed so that I have easy access to both kids, have space to change their clothes, put sunblock on in the summer, jackets on in the winter etc without ever leaving the car. Also the 110 pound dog lays there on long trips.
Could I use that seat without latching it or just one of the latches? The latch is really just to protect the other passengers in the event of a crash where he's not in the seat right? I noticed the latches are long and don't tighten.
