Boasting functionality that's key to a safe, smooth ride, the CYBEX Aton G Swivel is the first infant car seat to feature both 180-degree rotation and an anti-rebound bar for advanced crash protection. The base provides an ergonomic, 180-degree swivel that makes it easier to load and unload your little one while the seat is installed in the vehicle. Advanced safety features, like the anti-rebound bar and linear side-impact protection, reduce collision forces in the event of a crash. The Bluetooth-enabled chest clip provides real-time, in-app alerts when potentially unsafe situations arise: including if a child unbuckles the chest clip, if the back seat becomes too warm or too cold, and if the driver unintentionally leaves the child behind. Easy to handle at just 9 pounds, this lightweight car seat also includes an adjustable headrest and no-rethread harness, in-shell air ventilation for natural airflow, and a safelock belt tensioner for quick and easy installation.
