Britax Römer Swingfix i-Size seat is among the best ones in the ADAC, 2018 test. It was tested in the i-Size (up to 105 cm) category together with other 13 seats. ADAC rates it a safe, but extremely heavy seat (16,3 kg) that can be used from birth, but only in rearward-facing position. Even though it is also for newborns, it cannot be used as a carrier – for instance for me it would have never been a problem as I never used a safety seat as a carrier, I preferred putting them into a carry-cot on the pram and I simply carried them in my hand when we went to the car. However, you might consider if it is a problem for you before purchasing.


  • You can put your child into the seat easily thanks to its lateral rotation towards the door.
  • The cover is removable and can be washed in a washing machine.
  • A newborn insert is included for maximum safety and comfort for the smallest ones.
  • You can turn the seat by 90 degrees when the car is parked so that you can place in your child easier.
  • The rebound bar can be adjusted by 8 degrees to make your seat perfectly fit on your car seat and to give extra leg room for your child.
  • Superior Side Impact Protection (called SICT) keeps your baby out of harm coming from a side crash and absorbs the energy.
  • By using a rearward-facing seat longer, you protect your child’s head and neck which are not strong enough at this age.
  • The seat is designed to be put into several recline position to find the one that best suits your baby’s age and mood.
  • The side wings are deep and softly padded to provide comfort and safety.
  • V-shaped headrest controls the child’s unintended head movement while on the go.
  • A 5-point harness is not even comparable with a 3-point one – so it is not a question that Britax Römer only provides seats – obviously including Swingfix – with a 5-point harness.
  • The support leg’s height is adjustable to fit in your car.

The seat is available in 5 different colors.
