There's no latch system in the 3rd row, so you'll need to belt the car seat(s) in - remember to use retaining clips/locks on the seat belts to keep everything firmly in place! There are anchor points for the rear tether strap for each seat - the anchor points are under the lip of the floor that runs along the tailgate. I put kids in the rear occasionally - narrower car seats help if you are going to put two back there; I've never done in on a long trip, just around town (ie, when out with friends that also have kids), but presumably it's a comfortable there as in the second row...
