With the FLEX BASE iSENSE, you are ready for four years of convenient safety on the road. The modular base is compatible with the BABY-SAFE iSENSE and the new BABY-SAFE 3 i-SIZE, as well as the DUALFIX iSENSE ? and each of them can be installed on the base with just one click. The rotating feature allows you to turn each seat towards the car door, making it easy to place and harness your child. Additionally, the DUALFIX seats can be turned 360 degrees, allowing forward-facing travel when your child exceeds 15 months and 76cm. Features: Modular Base system - The modular FLEX BASE iSENSE is compatible with the BABY-SAFE iSENSE, the BABY-SAFE 3 i-SIZE, and the DUALFIX iSENSE. Easy access - The rotating feature of the base allows you to turn the seat to the car door, allowing you to easily place your child in and out of the seat. Adjustable rebound bar - The rebound bar not only helps to prevent the child car seat from tilting in an impact, but can also be adjusted by an entire 8 degrees. This allows you to easily adjust the rebound bar to the backrest of the vehicle seat and gives your child 10% of additional leg space. Adjustable angle optimisation - In cars with inclined vehicle seats, there may be a risk of your child's head tipping forward especially when they fall asleep in a car seat. With our FLEX BASE iSENSE you can easily adjust the angle of the car seat to six different positions, to provide a more ergonomic yet safe position of your child during any journey and in any car. The Britax Römer Pivot Link ISOFIX System - In case of an impact, our patented Pivot Link ISOFIX System directs the force first downward (1), into the vehicle seat, and then forward (2), more gently ? greatly reducing the risk of head and neck injury for your child. Smart and adjustable support leg - The support leg provides extra stability for the infant carrier base via the vehicle floor. It minimises the tilting and rotational movement and reduces the forward movement forces exerted on
