ARRA flex Infant Carrier — Lightweight, i-Size, 157° Recline (NEXT system)
With three recline positions — including a relaxed 157° lie-flat mode — the ARRA flex lets your baby ride almost fully reclined whether used with the BASE next, BASE curv, vehicle belt installation, or as a travel system on a stroller. It’s ultra-light (3.9 kg), meets i-Size R129, and blends innovative safety with ergonomic comfort to give you maximum freedom on every trip.
