Britax DualFix M i-Size Car Seat - Moonlight Blue

Britax DualFix M i-Size Car Seat - Moonlight Blue is a Group 0+& 1 Car Seat suitable for children from 61 to 105 cm tall. This i-Size Car Seat has a 360 rotation in the base that allows it to swivel from rear to front facing with ease. Keeps your child rearward facing for longer.

Why Should I Choose Britax DualFix M i-Size Car Seat - Moonlight Blue?

Britax DualFix M i-Size Car Seat - Moonlight Blue is suitable as a rearward facing follow-on to any newborn carrier. This i-Size Car Seat is suitable once your child reaches 61cm, so around 3 months. Once they reach 76cm, you can change to forward facing if you wish.

Swivel Seat

The swivel seat makes life so much easier. You can go from forward to rearward facing in a flash. Moreover, parents love how you can rotate the seat 90 degrees to face the door. Instead of twisting and reaching to get your child in (and buckle them up), simply turn the seat to face you.

Safety Credentials

This car seat surpasses the requirements of the current standard ECE R129 (i-Size). For example, the side impact protection SICT uses reinforced steel, creating a protective cage against front, side and rear impacts.

Advanced Side Impact Protection

Impact Protection Integrated SICT provides optimum protection in side collisions. In addition, Britax Romer Pivot Link ISOFIX System directs the force first downward and then forward, to reduce the risk of head and neck injury.

Rearward Facing 

Britax DualFix M i-Size Car Seat - Moonlight Blue has an adjustable rebound bar to reduce the seat tilting in a collision. As your child grows, simply adjust the bar a few degrees to create 10% extra legroom for your little one. Just another way Britax makes it easier to stay rearward facing for longer.

Comfort On The Road

This car seat has soft padded sides and a deep V which mimics the natural movement of your child's head. For naps and relaxation, the seat reclines into six different positions (forward and back).

Chest Pads

Neoprene chest pads are soft, strong and easy to wash - and you don't have to re-thread the harness as you do it, either. The harness itself disperses impacts into 5 different places, reducing the likelihood of injury.

Extra Stability

A height adjustable support leg provides extra stability and helps to stop the car seat tilting forward in a crash. Moreover, the colour indicators ensure you've fitted it correctly to your vehicle floor.

Machine Wash Cover

Can't take any more crumbs and stains? No problem. Just remove and machine wash the cover of the Britax DualFix M i-Size Car Seat - Moonlight Blue to get it looking bright and fresh once more.
