Update: It looks like the
Sunshine Kids Radian seats will work! In fact, it looks like we will be able to get away with using just one, and using the bottom parts (only) for our existing
Graco TurboBooster booster seats on the left and right in the rear row. (By removing the backs, which the
TurboBooster lets you do for kids 40 pounds and over, which ours are, we can give the kids who sit in the
booster seats enough access to the seatbelt sockets to buckle themselves in, as they do now.
Since the store I was at had two
Radians in stock, I was able to see if I could get two into the rear row, one in the middle and one on the side. Since they fit, I believe I could get 3
Radians into the rear row at a time, if that became desirable or necessary. I might want to double-check with 3 seats, just to make sure.
