The Britax KID SICT boasts air-filled side cushions for extra safety. They’re a reassuring addition, but certainly bulk up the car seat.


The Britax KID SICT is a Group 2/3 car seat, suitable for children from 15kg to 36kg, or about 4 to 12 years. It’s a high-backed seat without its own harness, which means that you use your car’s own seatbelt to secure your child.

The KID SICT is one of three new Group 2/3 car seats from Britax that feature ‘SICT’, or side impact cushion technology. The idea is that if your car is hit from the side, the air-filled cushions on each side absorb the energy of the impact, keeping your child safe.

The side cushions weren’t at all what I was expecting – I thought they’d be like airbags, but they’re actually rigid, plastic side wings. They make the car seat look a bit odd to begin with, as it’s so much wider than a standard seat.

What we love

Fitting the Britax KID SICT is very straightforward. It’s light and easy to move from car to car, and the back of the seat slots easily onto the base – I have another high-backed booster that comes apart at the drop of a hat and makes me swear every time I try to put it back together, so I appreciated this feature! The slots for the seatbelt are clearly signposted in bright red, so it’s impossible to get it wrong.

There’s no doubt that this car seat feels extremely safe. Usually when your child moves up from a Group 1 to a Group 2/3 you feel that they aren’t quite as secure, but that’s not the case here. It’s not just the SICT that makes it feel safe, either – the side wings come right around the sides of my son Jamie’s body, and the headrest is also very deep and protective.

This adjustable headrest, the wedge to make the seat recline, plus the lovely padding on the seat make this a very cosy, comfy car seat. My son really likes sitting in it, and the nice deep wings of the headrest mean that he can sleep comfortably on long journeys without his head flopping around.

The other thing that was pleasantly surprising was the price. It’s not cheap, but there’s not much difference between the pre-existing KID seat and the new one with SICT, so you’re not being charged a high premium for additional safety features.

What to watch out for

The Britax KID SICT is very wide. If you have two or fewer children to fit in the back seat you’ll probably be fine, but Jamie is my third son, so I have three seats to cram in the back of my estate car. I imagined that once we’d ditched the enormous Group 1 seat, things would be a bit roomier back there, but with the KID SICT this isn’t the case. My older two boys have more standard sized high-backed booster seats and they complain about how wide the top of Jamie’s seat is, and how it gets in their way. For some parents, a compact seat that fits better into the car will need to be the priority over the safety of the side impact cushions.

Who is the Britax KID SICT best for?

Families after top-notch safety for their older child, who have fewer than three children or a very big car.


MadeForMums verdict

The Britax KID SICT  is a car seat with lots of fantastic plus points: it’s comfy, good looking, easy to use and very safe. However, its bulk will be off-putting for some, and makes it a less practical choice for those with smaller cars or larger families.
