An infant seat is a type of car seat designed specifically for young children, typically from birth to about 2 years old. It provides a secure and comfortable way to transport infants in vehicles. These seats are rear-facing, which is the safest position for young children, as it helps protect their head, neck, and spine in the event of a collision. Most infant seats come with a base that remains in the car, allowing parents to easily click the seat in and out for convenience. They are often lightweight and portable, making it easy to carry the baby in and out of the car. Many models also feature adjustable harness systems and removable covers for easy cleaning.
