Product Details

Depending on the make and model of your car, you may find that your baby's head tips forward in their infant carrier, Britax Romer have considered this and designed the BABY-SAFE i-SIZE Flex Base lets you adjust the base angle to a flatter position, providing the most ergonomic position for your baby while travelling. This base is compatible with both the BABY-SAFE i-Size and the BABY-SAFE2 i-Size infant carriers.

  • Offers a more convenient way to install car seat
  • Gives greater stability for your car seat
  • Install safely in seconds with ISOFIX connectors
  • Flex base to get the right angle in every car

All about me

Does your vehicle have an inclined seat? The base can be adjusted to 4 different positions for the comfort of your baby, and also includes a handy indicator to show you when the angle is too flat. This base features a fold-away, height adjustable support leg for extra stability, minimising any tilting and rotational movement and therefore reducing the forward movement forces exerted on your child in a crash helping to protect them. Carry handles are integrated into the front and side of the base allowing you to more easily carry the base, and a ratchet system allows the ISOFIX arms to extend so that fitting the base to the anchorage point is simple and safe.
