Marble Edition: The Dualfix i-Size Marble Edition features premium fabrics in a smooth denim look for a sleek & stylish look.

360 Degree Rotation: With the press of a button, you can easily turn the Britax Romer DUALFIX i-SIZE Car Seat seat 360 degrees. You can seat your child securely in the car seat and rotate the seat into either the rear or forward facing positions, where it clicks firmly into place. 

Adjustable Support Leg: The support leg provides extra stability for the car seat via the vehicle floor. It minimises the tilting and rotational movement and reduces the forward movement forces exerted on your child in a crash situation, helping to protect them. For a secure installation, the support leg can be adjusted to suit the height that’s best for your car. The easy-to-read indicator shows you when the support leg is positioned firmly on your vehicle’s floor.

Comfort Features: The Britax Romer DUALFIX i-SIZE Car Seat has 12 recline positions, 6 forward and 6 rearward facing. There is also machine washable fabric that can be removed without undoing the harness.

5-Point Harness: The 5-point harness is the safest way to secure your child in a car seat - it will keep your child safe and secure in the seat’s protective shell. In the event of a collision, the harness distributes the forces of the impact across 5 points, two at the shoulders, two at the hips and one where the harness buckles between the legs. Soft neoprene performance chest pads fit comfortably on your child’s chest to reduce movement in the event of a collision.

Rebound Bar: The rebound bar not only helps to prevent the child car seat from tilting in an impact but can also be adjusted by 8 degrees. This allows you to easily adjust the rebound bar to the backrest of the vehicle seat and gives your child an additional 10% of leg space. 

Superior Side Impact Protection: SICT offers superior protection in case of a side collision in two steps. It pushes your child away from the impact in a controlled movement and then deforms to absorb energy exerted on your child. The SICT can be adjusted to suit your car. 

Protective Side Wings: The deep, soft padded protective side wings act as a protective cocoon for your child. The specially designed V-shaped headrest ensures optimal protection in the event of a side collision while providing ultimate comfort at the same time. The headrest and harness can easily be adjusted from the front of the seat to suit your child’s height.
