Hi Bob, Yes you can. With plenty of space to spare for getting your hands down between the seats to fasten the buckles on the boosters. I have a 52 reg 1.9 TDi and have one normal child seat, fastened in with the seat belt and a 5 point harness for the child, plus two high back boosters across the middle row and there's plenty of room. I also find it is easier to fix the normal child seat in as you can get right on top of it when tightening the seatbelt. The only problem I found was that with some seats didn't seem to fit very tightly. I got a Britax Evolva 123 and had to go back to the shop to get it fitted properly. I wasn't putting enough weight on it to get it tight as the seat cushions are well padded and have a lot of give in them. Now as I know what I'm doing though I have no problem fitting it back in. Hi That sounds great! Thanks. Are you happy with the Galaxy? Bob
