One-second installation

Save your strength for more important parenting battles and let ISOFIX connectors do the hard work for you… our handy install indicators mean you get a flawlessly firm installation without going to war in your backseat.


Heavy on safety, not bulk

We managed to bulk up the safety without bulking up the mass… At less than 10kg, this lightweight makes easy work of loading up.


Made to grow with them

We engineered this long-term seating solution with growth in mind. A deep shell and extendable rebound bar offer plenty of legroom as they grow up. An 8-position recline accommodates children of all sizes and lets them cruise in comfort.

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.
