The Britax Römer ADVANSAFIX i-Size is a fully equipped forward-facing car seat, suitable for children from 76 to 150 cm (approx 15 months to 12 years old). Based on the award-winning ADVANSAFIX IV R it includes advanced safety features like additional adjustable side-impact guards ( SICT) and special XP PAD. This special overlay can be attached to the vehicle seat belt adding extra protection to your child‘s neck and chest.

The ADVANSAFIX i-Size also comes with a strong 21 kg harness, V-shaped headrest and SecureGuard belt-positioning system, which reduces abdominal forces in the event of a frontal collision by up to 35 %.

The FLIP&GROW function allows for easy change between integrated 5 point harness and 3 point seat in few simple steps. This smart solution keeps all compartments together, so you don't need to remove any parts from the seat, nothing can get lost, and you can swap it back at any time.

The extra soft neoprene chest pads fit conveniently on your child’s chest, helps to reduce their movement in the event of an impact. In addition, you can easily remove these for washing without disturbing the harness.

The Britax Römer ADVANSAFIX i-Size can be installed in your car by standard ISOFIX installation points with Top Tether (76 - 102 cm) or vehicle's 3-point seat belt (100-150 cm) with optional ISOFIX connection.
