@Carlie I have the VW Touran which can fit 3 car seats in the back, I currently have 2 isofix car seats and the joie every stage but obviously one is in the middle so I have no clue how I’m going to reach the middle to put the kid in the middle in if you get me 🤣
I have the Joie iSpin Grow that spins and goes up to 7 x
We have an Osann spin that does up to 12 can’t remember exact model
Ahh have a look at the sliver cross 360 which goes up to 12 year that’s what I have at the moment
I have the exact same dilemma, not sure what car you have but there aren’t many that have 3 isofix points in the rear the only solution I have found is the multimac which is a bench which fits across the back seats.
