Harmony Youth Booster Elite

The Youth Booster Elite is a lightweight backless booster that earned  average scores for belt fit in our tests. The exceptionally lightweight (only 3 pounds) may make it a good option for travel or carpools. And the seat’s narrow width helps it score well for fit-to-vehicle even in highly contoured vehicle seats.

As a backless booster, the Youth Booster is only appropriate for use with children at least 4 years of age who also meet the weight and height requirements set by the manufacturer. Once your child outgrows their forward-facing child car seat by weight or height, CR and the American Academy of Pediatrics (AAP) recommend that kids use boosters until they are at least 4 feet 9 inches tall, are 8 to 12 years old, and have the developmental maturity to keep their belt properly positioned for an entire car ride.

The Harmony Youth Booster Elite is part of the Car Seats test program at Consumer Reports. In our lab tests, Booster Seats models like the Youth Booster Elite are rated on multiple criteria, such as those listed below.

Booster fit (with back): A rating that reflects a booster seat's ability to correctly position the lap and shoulder belts in various test vehicles using a child-sized dummy, when used as a highback booster. Additionally, it includes an assessment of the booster's compatibility with vehicle seats and interior components.

Booster fit (no-back): A rating that reflects a booster seat's ability to correctly position the lap and shoulder belts in various test vehicles using a child-sized dummy, when used as a backless booster. Additionally, it includes an assessment of the booster's compatibility with vehicle seats and interior components.

Ease of use: Our evaluation of how easy each seat is to use, including items such as the clarity of labels and instructions, the ease of achieving an appropriate belt fit, and the transition between highback and backless modes where applicable.
