A convertible car seat is a type of child safety seat that can be used in two different modes: rear-facing and forward-facing. When used in the rear-facing position, it provides the best protection for infants and toddlers, as it supports their head, neck, and spine during a crash. As your child grows, the seat can be turned to face forward, accommodating larger children up to a certain weight limit. These seats are designed to be versatile and can often be used for several years, making them a cost-effective choice for parents. Many convertible car seats also come with adjustable features, such as harness systems and reclining positions, ensuring comfort and safety as your child develops.
