Product details

The Britax Römer Baby-Safe Core is a safe and comfortable car seat specifically designed for newborns. Weighing only 3.9 kg, it is easy to handle even when the child is already seated. The seat offers a combination of advanced safety features and practical functions that facilitate transport between the car and home. The sturdy carrying handle can be fully rotated backward, making it easier to place the baby and secure the integrated harness. The seat can be installed rear-facing in the car, either using the vehicle's 3-point seatbelt or with a separately available ISOFIX base. For newborns, the seat is equipped with removable seat wedges that provide additional support and enhance comfort during travel. An adjustable headrest area and an extendable sun canopy with UV50+ protection complete the thoughtful design. Additionally, the travel system allows for easy attachment to certain Britax stroller models.

  • ECE R129/i-Size safety standard
  • Rear-facing installation for optimal safety
  • Removable seat wedges for added comfort for newborns
  • Adjustable headrest in 10 positions
  • Extendable sun canopy with UV50+ protection.
