This child car seat has passed the regulatory tests required by ECE R44/04 to be sold as a group I/II/III car seat suitable for children weighing 9-36kg, which is one to 12 years of age. But in our own tests, which are conducted at higher speeds and forces than the standard requires, this seat scores poorly for side-impact tests. The head of the crash test dummy hit the inside of the test vehicle. We also identified issues with installation and fitting which could mean the seat is not used as safely as it should be. Any car seat scoring 45% or less becomes a Which? Don't Buy.

Safety rating

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.
