Overview
The Evenflo CS500312203 is a booster car seat rated for children up to 100 pounds, installed with either the vehicle's latch anchors or its seat belt, aimed at the toddler stage rather than infants.
A 100 pound weight capacity puts this seat well past the infant and convertible stages, into booster territory meant to carry a child through much of early childhood. The dual latch and seat belt installation options give some flexibility depending on the vehicle.
- 100 pound weight capacity
- Latch and seat belt installation
- Booster car seat orientation
Who it's for
Parents moving a toddler into a booster-style seat who want the option of either latch or seat belt installation. Not the right pick for a newborn or infant, given the toddler age range and booster orientation.
Pros and cons
- 100 pound weight capacity covers an extended toddler range
- Installs with either latch or seat belt
- Booster orientation is not suited to infants
Performance notes
The polyurethane foam lining is the main energy-absorbing layer, and the booster orientation means the seat works with the vehicle's own seat belt path across the child rather than a built-in harness at higher weights.
