just found it on the graco website. the Nautilus is 20" wide - that's 3" wider than the radian. my current configuration of three seats - one Safeseat that is 19", one Radian 65 that is 17", and an Evenflo Chase that is 17" - that's 53" total... the configuration of seats i'm considering (Radian 65 for the baby RF, and two Nautilus' for the 3 and 5 yo) would be 57"... it's seems pretty tight in there as it is, though there is a couple inches between edge of carseat and edge of actual seat on each side. would a store like Target (if they have the Nautilus) let me try them in the car before i bought them?
i have latch for the two outboard seats but not the middle. but atm i have them installed with the seatbelts anyway because when we bought the car i forgot all about latch (my old car didn't have it at all)
and i prefer to keep the baby behind the driver's seat if possible because 1) it's easier for me to get her in and out, and 2) i don't want DS messing with the baby. and i really don't want to put DD1 in the third row because not only does it mean loss of major trunk space but she can buckle herself into a harness just fine but can't get herself out, so i'd have to climb back there every time we got out of the car, which doesn't thrill me.
hmmm.... must go measure my back seat
