Britax DualFix M i-Size Car Seat - Cosmos Black

The Britax DualFix M i-Size Car Seat is designed to remain in the car as a flexible follow on seat to any infant carrier.  Suitable for children from 61 to 105 cm tall, it can be used in both rearward and forward facing positions thanks to the 360 degree rotation system in the base.

Why should I choose the Britax DualFix M i-Size Car Seat - Cosmos Black?

The Britax DualFix M i-Size Car Seat is a flexible follow-on seat to any infant carrier - suitable for children from 61 to 105 cm tall (or approximately 3 months to 4 years) in the rearward facing position and from 76 - 105 cm in the forward facing position. This car seat is designed to remain in the car. Thanks to the 360 degree rotation system in the base, it is easy to switch the seat position as required. Also, you can turn the seat 90 degrees to face the open car door which is perfect for getting your child in and out and doing up the harness. 

Safety Reinforced with Steel There are no compromises in this car seat's safety benefits which are more vigorously applied than those of the current standard ECE R129 (i-Size). For example, the side impact protection SICT built into the seat uses a special steel element for strength. This ensures that your baby is well protected in the event of an accident, whether it is from the front, from the side or from the back. The Britax DualFix M i-Size Car Seat has been developed, designed and manufactured in Germany, and it has only been approved after exhaustive tests in Britax's state of the art crash test facility. 
Impact Protection Integrated SICT inside offers your child superior protection in the event of a side collision, it also keeps your child away from the impact while absorbing energy at the same time, so you don't have to adapt or adjust anything - SICT inside is always ready when you need it. In case of an impact the patented Britax Romer Pivot Link ISOFIX System directs the force first downward (1), into the vehicle seat, and the forward (2), more gently - massively reducing the risk of head and neck injury.  

Rearward Facing for longer The Britax Dualfix M i-Size Car Seat has 12 recline positions - rearward and forward facing.  It also has an adjustable rebound bar which helps to prevent the child car seat from tilting should there be an impact, but can also be adjusted by 8 degrees to let you easily fit the rebound bar to the backrest of the vehicle seat giving your child 10% of extra leg space. This allows your child to stay facing the rear of the car until they are a little older.

Protective Cocoon The Britax DualFix M i-Size Car Seat features soft and padded side panels that act as a protective cocoon. Specially designed to control the movement of your child's head, the V-shaped headrest ensures a high level of protection in the event of a side collision and is super comfortable at the same time. The car seat headrest and harness are easily adjusted from the front of the seat.

Chest Protection The new, soft neoprene performance chest pads on the Britax DualFix M i-Size Car Seat fit comfortably to minimise your child's movement should there be a collision. These pads can be easily taken off for washing without having to move the harness. The 5-point harness evens out the force of any impact: two points at the shoulders, two at the hips and one where the harness buckles between the legs. This diffusion of force protects your child from all directions of impact.

Secure Fitting The height-adjustable leg on the base provides extra stability for the car seat. By adjusting and positioning it against the floor of your car the leg cuts down any tilting and rotational movement and reduces any forward movement in case of accident. The easy-to-read indicator shows you when the support leg is firmly positioned on your vehicle's floor.

Easy to clean Inevitably on a long journey, things can get messy: drinks can spill and treats can get smeared over the sides of the chair. The machine washable car seat cover can easily be taken off without removing the harness, so you can clean up quick and are ready for next time.
