Overview

For those busy days and long journeys, the ARRA flex infant car seat provides a smooth transition from crib to carrier. Its three recline positions, including a relaxed 157° recline position, allow baby to lie comfortably whether installed using one of the many flexible options in your vehicle or attached to a pushchair.

The lightweight ARRA flex is i-Size approved and offers innovative safety features along with ergonomic advantages that provide you and baby with the ultimate freedom for every journey.

Important Notice: If you use the BASE curv with ARRA flex, the same base must not be used with the TODL next seat at any time. The BASE curv is not intended to be used as a modular system with both seats.
