A convertible car seat is one of the best investments you can make for your child’s safety. Unlike infant seats, convertible seats grow with your child from rear-facing infant through forward-facing toddler — saving you money and keeping your child safer longer.

Why Go Convertible?

Rear-facing is the safest position for young children. Convertible seats allow you to keep your child rear-facing longer — up to 40–50 lbs on most models — which pediatricians and the AAP strongly recommend.
