From Which report:
BeSafe Izi combi x2:
This group 0+/1 seat is designed to carry children from birth up to 18kg (about four years) - rearward-facing up to about 13kg (about a year) and then forward-facing. It is secured using the seat belt.
Head support is good, but it lacks leg support for larger children and longer journeys. Crash performance is good in a side crash, and in a head on collision front crash loads are acceptable.
The seat is heavy. You can adjust the seat height and the harness length and height without dismantling it, but it?s very complicated to install in the car and is liable to be installed incorrectly as a result. This is a serious problem, and as a result the seat falls below our safety threshold and is rated as a Which? Don?t Buy.
The finish quality of this seat is very good, and cleaning the cover is straightforward as it?s machine-washable.
Pros: Good finish quality
Cons: Difficult to install, cleaning the seat cover is complicated, big and heavy ? a particular problem in smaller cars.
Front crash 3/5
Side crash 4/5
Overall safety 3/5
Britax Multi-tech/Volvo (same seat):
We recommend you avoid the Which? Don?t Buy Britax Multi-Tech, a group 1/2 seat (also sold in the UK by Volvo dealers as the Volvo Convertible child seat). It is secured using the adult seat belts and aims to cater for children between 9 and 25kg (from about one to about seven years old).
It comes from Britax?s Nordic range, and although it isn?t listed on the Britax UK website, it is available at some specialist UK independent retailers. For group 1 it is installed rearward-facing, and for group 2 use it fits forward-facing. The seat takes up a lot of space in its rearward-facing position, which can cause problems in smaller cars.
Unfortunately, in trying to cater for different uses, it makes too many compromises. This results in poor protection, with the child exposed to fairly high loads in a front crash.
Despite having fairly clear instructions, it is also very complicated to install in the car, making the likelihood of getting it wrong unacceptably high. If you do manage to install it correctly, buckling the child in the seat is relatively straightforward.
The seat is nicely finished and offers good head support, but leg support could be better. The seat cover is handwash only.
Pros: Buckling up easy, good padding, good finish quality
Cons: High loads in a front crash, complicated installation, removing and cleaning the seat cover is complicated.
Front crash: 2/5
Side crash 3/5
Overall safety 3/5
Both 2/5 for fitting in car.
