This child car seat has passed the regulatory tests required by ECE R44/04 to be sold as suitable for children from 9-36kg. But in our own tests, which are conducted at higher speeds and forces than the standard requires, this seat still scores poorly for frontal-impact results when used in Group 1 mode. Any car seat scoring 45% or less will become a Which? Don't Buy.

The Joie Every Stage is the 'ultimate transporter', according to the manufacturer. It's a multi-group child car seat approved for use from birth up to 36kg, which is around 12 years old - or when your child may no longer need a car seat. It's installed using your car's adult seat belt. In our tests, some multi-group car seats don't always work as well as separate seats. This multi-group car seat is a Don't Buy. See the safety alert attached to this review for more information.

How we test safety rating

The overall safety score is made up of the results of crash testing (front crash; side crash) seat design, stability in the car and belt routing. Our crash tests go beyond the legal minimum requirements for UK car seat regulations and are conducted at higher speeds and forces than the regulations require. We feel our tests more accurately reflect what could happen in a real life crash.

How we test fitting in car

Fitting and using includes: How easy it is to install the seat correctly in the car. How easy it is to strap a child securely into the seat. How well the seat is designed in order to prevent incorrect use. How easy the seat cover is to remove and wash. How little space the seat takes up in the car and how comfortable your child is in the seat.

Ergonomics

Overall
Comfort of your child

How we test ergonomics

Our experts conduct an ergonomic assessment of each seat to make sure your child will be in the best position when travelling, along with the level of padding and support. Our tests also reveal how much space this car seat takes up in the back seat of a car and how easy it is to get your child in and out of the seat. Plus, our eagle-eyed car seat experts will check whether this seat affects how much space any front passengers have. This assessment was introduced to our site in May 2015. If a seat does not have this score, it was tested before May 2015.
