Infant seats are specially designed car seats that provide safety and comfort for babies during travel. They are typically rear-facing and come with a five-point harness system to secure the child. These seats are essential for protecting infants in case of an accident, as they are designed to absorb impact and keep the baby in a safe position. Many infant seats are also portable, allowing parents to easily carry their little ones in and out of the car. Some models can be attached to strollers, making it convenient for parents to transition from driving to walking without disturbing the baby.
