1. Introduzione e oltreview
The Evenflo Maestro Sport Harness Booster Car Seat is designed to provide safety and comfort for your child through two distinct stages of growth. This 2-in-1 car seat transitions from a 5-point harness car seat to a high-back belt-positioning booster, accommodating children from 22 to 110 lbs.
Key features include dual integrated cup holders for convenience and an up-front harness adjustment for easy and proper tightening. The Maestro car seat is proudly designed, engineered, tested, and assembled in the United States, exceeding industry standards through rigorous side impact and dynamic rollover tests.
