Britax Römer Dualfix M i-Size Car Seat

The Britax Römer Dualfix M i-Size car seat in Moonlight Blue is an i-Size compliant car seat designed for prolonged use, accomodating children from approximately 3 months to 4 years in both rearward and forward-facing positions. 

360-Degree Rotation

The base of the Dualfix M i-Size features a 360-degree rotation mechanism, which allows you to rotate the entire seat unit towards the door of your vehicle during loading and unloading of your baby, making it easier to correctly fit the harness and reducing the strain placed on your back due to twisting and lifting when removing your little one from their seat. It also allows for quick and easy transitioning between rearward and forward facing positions, so if you decide you would like to make the switch to forward facing it is not necessary to remove and reinstall the seat unit. It is important to note that Britax Römer recommend rear-facing travel for as long as possible as it is proven to be safer in the event of a collision, therefore the Dualfix M i-Size can be used entirely rear-facing all the way up to the 18 kg weight limit. 

Impact Protection

The Dualfix M i-Size is fitted with integrated SICT (Side Impact Cushion Technology) that offers superior protection for your child in the event of a side-impact collision, keeping your child away from the impact whilst simultaneously absorbing force and energy before it reaches your little passenger. The SICT system utilises a special steel element that provides strength, which is built into the shell of the seat and helps protect your baby from all angles, keeping them as safe as possible during an impact from any side. 

The interior of the seat unit provides a protective cocoon for your little one thanks to softly padded side panels and a V-shaped headrest that's designed to control the movement of your child's head, keeping them safe in the event of an accident and providing unbeatable comfort day-to-day. Finally, the Pivot Link ISOFIX System keeps baby safe in the event of a front-on collision, directing force initially downwards into the vehicle's seat and then gently forward, greatly reducing the amount of force exerted on the head and neck.
