10 i-Size car seats to watch out for in 2017

Latest developments to help keep your baby safe

Maxi Cosi AxissFix PlusMaxi-Cosi AxissFix Plus is now suitable to use from birth thanks to an inlay

2017 promises to be an exciting year for i-Size child car seats as more and more manufacturers enter the market with new car seats approved to the latest safety standards. 

i-Size car seats are approved to the latest car seat regulations (R129) which came into force in the UK in 2015. Many of the first i-Size car seats were designed as modular systems, so you needed one seat for your baby and then another for your toddler, but now we’re seeing many more developments for seats to last from birth until your child reaches 105cm tall, which  is usually around four years of age.

New i-Size child car seats

We’ve rounded up ten new car seats that caught our eye at the latest Kind und Jungen baby exhibition in Germany, so you can start planning your new baby purchases.

Britax Baby Safe i-Size

Britax entered the i-Size car seat market later than other manufacturers, but is making up for it now with an exciting range of i-Size car seats planned for release leading up to 2017 and beyond. First up is the BabySafe i-Size, which is due later this year. This can either be  bought with an i-Size base or i-Size Flex base.
