Top 5: Used Cars That Can Fit 3 Child Seats in the Back

06th Apr 2021

Need a car that can accommodate three child seats in the back?

When transporting children in cars it is important that they are comfortable and safe. Luxury SUVs are more popular than ever in the UK thanks to their ability to transport families, as well as receiving improvements in driving dynamics, fuel economy and styling in the past few years.

In the UK children up to the age of 12 years old or 135 centimetres tall, whichever comes first, are legally required to sit in a child seat. Due to this, some larger families require a vehicle with adequate space in the rear for three child seats. However, it can be difficult searching for a luxury car that meets all of your specific requirements as well as fitting three or more child seats in the back as even some of the largest SUVs do not feature ISOFIX points on more than two of their rear seats.

With this in mind, we have created a list of five luxury cars that provide the space for three child car seats in the back and have at least three seats with ISOFIX/i-Size fixing points.

The GLS is Mercedes-Benz's largest and most luxurious SUV, indulging up to seven passengers with a deluxe interior and extravagant entertainment.
