Child Weight 5-65 lbs



Evenflo® is raising the bar on safety with Lyf Guard™™, the next level of advanced side impact technology. Lyf Guard™ incorporates multiple layers of energy-absorbing materials that are designed to compress upon impact, helping to lower the risk of injury. In addition to Lyf Guard™, each Pro Series Stratos™ Convertible Car Seat is structurally tested for safety in the event of a rollover accident for built-in safety from every angle! To further encourage safety, the Pro Series Stratos™ is weight-rated for up to 40lbs rear-facing and up to 65lbs forward-facing so your child can remain harnessed longer. This seat also includes a 5 position adjustable headrest and 6 shoulder harness strap heights to provide a true extended fit option. For added comfort, we’ve built-in a ventilation system that enables a steady airflow for your child through all seasons. To make installation quick and easy, we’ve added our SureSafe™ Installation which is comprised of Quick Connector® technology and LATCH Guides, increasing proper installation by 2X compared to installation with standard LATCH hooks.
