Which cars carry three child seats?
Anything with seven seats – the Volvo XC90, the Audi Q7, the BMW X5 (with seven-seat option), the Hyundai Santa Fe, the Kia Sorento, the Peugeot 5008, the Nissan X-Trail, the Citroen Grand C4 Picasso (now the Grand C4 Spacetourer), the SEAT Alhambra, the Volkswagen Touran and more – can get three child seats in the back… arranged across the second and third row of seats. You’d put two behind the front-seat occupants and one in the back.
However, if you want all three child seats across the middle row, your choices are much more limited – as this is a tricky issue of space across the width of the car. Out of the list above, the only ones which have three ISOFIX points in the middle row are the Audi Q7 Mk2, the Citroen Grand C4 Picasso/Spacetourer, the SEAT Alhambra and the Volkswagen Touran. Of these, these Audi is extremely expensive, even used, so look for good, used examples of the others as your best bet.
Obviously, all of this depends on the bulkiness of your child seats, as that varies considerably, plus of course whether you need ISOFIX.
