The smarter way to ride with confidence

Choosing the safest car seat doesn’t have to be complicated… when

you buy an i-Size certified car seat that meets the highest ECE R129

safety standard, you’re investing in a seat that offers a guaranteed fit in i-Size approved vehicles, has an intuitive installation, and is tested by the most current European car seat standards.

ECE R129 or i-Size car seats… What’s the difference?

While ECE R129 and i-Size car seats undergo the same side-impact testing with advanced crash-test dummies, require mandatory rear-facing until 76 cm and 15 months, and use height instead of weight for proper usage; the terms differ in two key areas:

ECE R129

European safety regulation

ECE R129 refers to the most recent and safest European safety regulation that controls the manufacturing of car seas. The ECE R129 safety regulation provides better side-impact protection, requires rear-facing for longer, and makes it easier to find the best-fitting car seats for your child.

Enhancement of ECE R129


i-Size, on the other hand, is an enhancement of ECE R129 that makes it easier to confirm your i-Size car seat’s compatibility with any i-Size approved vehicle – reducing the risk of installing your car seat incorrectly. The idea behind i-Size is that all car seats will eventually fit in all cars. While all i-Size car seats meet ECE R129 testing standards, not every ECE R129 car seat is an automatic fit for vehicles with i-Size compatible seating positions.

When shopping for a car seat, ask for a car seat that meets the ECE R129 safety regulation. For simplicity, look for the yellow i-Size icon to verify that it’s suitable for your i-Size approved vehicle without the need to check the fitting list.


Alternatively you can ensure you’re purchasing a car seat that meets the highest ECE R129 safety standard and has i-Size certification by simply look for the “I” in front of any of our car seat names, for example ‘i-snug 2’.

How i-Size fits in

i-Size is an enhancement of ECE R129


Many of Joie’s car seats meet the newest and most advanced car seat regulation in the UK and EU, ECE R129. Even more of our seats have gone on to receive the additional i-Size certification to confirm a guaranteed back seat fit in an i-Size seating position.


Did you know when you buy i-Size, you’re also getting all of ECE R129’s safety and convenience features to make your rides safer and smarter?


Let’s see how i-Size compares to ECE R44 and ECE R129:

ECE R129 car seats that are eligible for the additional i-Size certification:

These will be tested to confirm a guaranteed fit in i-Sized approved vehicles. Car seats that pass the certification will showcase their i-Sized compliance with “i-Sized” indicators on the product, packaging or marketing materials.
