EXTENDED HARNESS

Shield a little longer

The 5-point harness fits children all the way up to 19.5 kg or 105 cm (approx. 4.5 years old), distributing force across their strongest body parts and removing risk of ejection during a crash.

STEEL REINFORCEMENT

Strong & secure

The reinforced steel shell sets an ultra-strong foundation for the i-Plenti™ car seat, providing rigid side impact protection that fights back against the strongest forces.

AUTO ADJUST™

Grow up & out

Your growing child won’t feel squished as they reach new heights: The AutoAdjust™ side wings automatically widen when you raise the headrest, giving your passenger more shoulder space to stay comfortable in their car seat.

3 POSITION RECLINE

Kick back & relax

With no reinstalling necessary, parents can quickly fine-tune the recline for customised comfort on the go.

SIDE IMPACT PROTECTION

Layers of safety

The reinforced steel shell sets an ultra-strong foundation, while the state-of-the-art Tri-Protect™ headrest features 3 layers of foam including Intelli-Fit™ memory foam. As an additional safeguard, a Guard Surround Safety™ pod connects to the outer side of the headrest to absorb impact during a crash.

The Signature difference

There’s nothing like slipping into a timeless staple piece: that’s the feeling you’ll get when you snuggle your little one into a Joie Signature pushchair or car seat. Go on, have your moment.

Our materials

We test for more than 150 different toxic substances to ensure your child's gear is safe even down to its basic ingredients.

Rated 5 out of 5 by from Great car seat Great car seat, got this as a second car seat for my husband’s car and my 19 month old loves it, so much she wants to go in daddy’s car. Really easy to fit and looks very safe, wish this had been our first purchase instead of another very expensive car seat

Rated 4 out of 5 by from Good car seat We bought this car seat recently and it's very sturdy. It's quite heavy if you need to move it in and out of the car and difficult to carry. My son is very comfortable in the seat and it's easy to fit.

Rated 4 out of 5 by from Brilliant car seat. We bough this car seat to upgrade from his joie 360 for my 3 and half year old. The seat is strong, sturdy and feels just as safe at the 360. There are magnets in the sides to attach the buckles to and to attach the buckles together for when you’re about to strap in. Which are brilliant as you can find the straps straight away. I would have put 5 starts for this car seat but due to the magnets we will be unable to use it for our daughter for when she is older who has a pacemaker located in her tummy. So due to the magnets messing with it if we use it we can’t use it for her. But this car seat is Brilliant and I would definitely recommend.

Rated 5 out of 5 by from Fantastic car seat for 4 years plus I was on the look out for something suitable, protective and comfy for my 4 year old. I honestly couldn’t find any reviews at all for this car seat. I did my research and although I found many others I liked the look of (and were cheaper in price) I always kept coming back to this one. In the end I decided to order it and I’m so glad I did. I love it. It’s stylish, extremely cosy and soft (according to my child) I love the safety features on it, the way it slightly reclines, I love the way head rest moves up when they grow and not only does the head rest move up but the side of the car seat get slightly wider as well (this is a great feature so they don’t feel squashed when they get older) I’m really pleased I purchased this. I have no regrets and I can’t think of any negatives. I’d say it is on the pricey side but this will last up until my child is 12 so I really don’t think it is that expensive for the quality at all. I wanted something nice that would last and I have found it and highly recommend. The car seat comes with extra padding as it is for 15month plus (I can’t comment on a child this age in it)
