Britax Romer Flex iSENSE Base

Britax Romer Flex iSENSE Base is a must-have base to install your Britax Romer DualFix iSENSE Car Seat, Britax Romer Baby Safe iSENSE Car Seat or Britax Romer Baby Safe 3 i-Size Car Seat onto. When used in conjunction with its compatible seats, this Car Seat Base offers 360 degree rotation, multiple recline positions as well as a base that fits two different seats on to, creating your very own Modular System.

Why Should I Choose Britax Romer Flex iSENSE Base?

One base, three seats. The Britax Romer Flex iSENSE Base is compatible with the Britax Romer DualFix iSENSE Car SeatBritax Romer Baby Safe iSENSE Car Seat or Britax Romer Baby Safe 3 i-Size Car Seat. What's more, it allows for super easy switching between the three. This modularity provides great comfort for the first four years with your child. With the use of this base, you can swivel your DualFix iSENSE 360 degrees, from rearward to forward facing. This feature also allows you to harness your child into the seats as they face the door. Use this base from birth, first with either infant carrier, and then with the DualFix iSENSE.

Adjustable Rebound Bar

Additionally, the rebound bar not only helps to prevent the car seat from tilting in an impact, but can also be adjusted by 8 degrees. This allows you to adjust the rebound bar to the backrest of the vehicle seat. Plus, it gives your child 10% of additional leg space. Simply click the ISOfix ratchet system into your vehicles ISOfix anchorage points. This system allows the ISOfix arms to extend so that you can easily fit or remove the base when needed. Once the ISOfix connectors are engaged, push the base until it touches the back of the vehicle seat. This prevents the infant carrier from lifting upwards in case of an impact.

Adjustable Angle Optimisation

In cars with inclined vehicle seats, there may be a risk of your child's head tipping forwards. This is especially when they fall asleep in the car. With Britax Romer Flex iSENSE Base you can adjust the angle of the Car Seat to six different positions. This provides a more ergonomic yet safe position of your child during any journey and in any car.

Smart Support Leg

Last but not least, the support leg provides extra stability for the Flex iSENSE Base via the vehicle's floor. It minimises the tilting and rotational movement, and reduces the forward movement forces exerted on your little one in a crash situation. For a secure installation, you can adjust the support leg to suit the height that's best for your car. The easy to read indictor shows you when the support leg is positioned firmly on the floor, changing from red to black when correctly installed. In addition, it will notify you with a sound if not correctly installed.
