The Britax Römer DUALFIX PLUS in Night Blue makes every journey safer and simpler, adapting as your little one grows. With 360° rotation, switching between rearward and forward-facing is effortless—and you can turn the seat towards the open door for easy access when getting your child in and out.

Designed for comfort from day one, the newborn insert offers extra support and a flatter, ergonomic position. Rearward-facing travel up to 105 cm (around 4 years old) provides maximum safety, helping to absorb crash forces more effectively in frontal collisions. With multiple recline positions, your little one stays comfy, whether they’re wide-eyed and exploring or drifting off for a nap.

The deep side wings add extra impact protection, while the one-hand adjustable headrest and 5-point harness grow with your child for a perfect, secure fit. Messy moments? No problem—the machine-washable seat cover removes easily without unthreading the harness.

For extra stability, the adjustable support leg reduces movement, with an easy-to-read indicator for a secure fit. Plus, the DUALFIX PLUS meets the latest i-Size (R129) safety standards, giving you peace of mind on every adventure.
