Narrow highback booster to fit between 2 Group 0 carseats-help please!

[Clare71]

DD is 6 and I am expecting twins in 4 weeks. We have a Hyundai Santa Fe and have bought 2 maxi-cosi cabriofix carseats with isofix bases as I felt that these were safer and would be easier to get both carseats in and out rather than fighting with seat belts! Only problem is that DD high back booster (Britax Evolva 23)doesn't fit between the 2 carseats. Does anyone know of a narrow highback booster that may fit. Ideally would like to keep isofix bases for other carseats. (Also DH was soooo sure they would all fit that he ripped all the labels off so can't return them!!)

Thank-you!

You could try a britax adventure this would be the easiest for you to strap in as it has no wings like other seats. It seams to be narrower were it matters. The other ones you can try is the graco higback and the ninia highback. You will need to take baby seats and bases with you and you may find it easier to not put the seat nearest the middle seats buckle until you have strapped her in. I would put you big one in the front when it is just you and the three children it will be hard enough getting out with three. Good luck.
