Three positions, one near flat
The ARRA flex offers three recline positions in both car seat and travel system modes. It converts to a flat reclining seat at a 157 degree angle for the car, the airplane or a pushchair. That angle keeps baby's head, spine and hips well supported. The seat is exempt from the 2 hour usage recommendation.
Protected from the very first ride
The ARRA flex is i-Size certified and meets R129 safety standards, which include side impact testing. EPP energy absorbing foam adds side impact protection. A removable newborn insert, a no rethread 3 point harness and a 10 position headrest keep the fit right as baby grows.
Flexible ways to fit your car
Install the ARRA flex securely with the vehicle seat belt, no base needed. You can also click it onto a NEXT system base, the BASE curv or BASE next. Each installs with a load leg and ISOFIX and rotates 360 degrees. It is TUV certified for air travel and ready for travel system use with compatible pushchairs.
