A car seat base’s primary function is to make it simpler for parents and other caregivers to quickly and securely install and safely remove the baby’s car seat.

Rather than installing the infant car seat directly with each use, you install the base once and then click the infant car seat into the base as needed.

Car seat bases are essential to keep newborns and young children safe when car traveling.

These bases are made to safely attach to the automobile’s seat, creating a solid surface for the car seat to click into.

To safeguard your child in the event of an accident or rapid braking, the car seat base must be installed correctly.
