What is a Convertible Car Seat?

There are many types of car seats available to new parents, but the convertible car seat is one that you will get A LOT of use out of! As the name implies, they can be used rear-facing from birth, then “convert” or transition to forward-facing up until approximately 65 lbs and 49″. [Make sure you check your owner’s manual to verify the height and weight limits on your specific model of seat!]

Between owning a retail baby store for 8 years, being a Child Passenger Safety Technician and prenatal and pediatric chiropractic for over 10 years, I take safety very seriously. To me, the car seat is the one item you can splurge on to ensure that your child is safe while traveling with the family. My expertise has helped me narrow down a list of TOP 7 BEST CONVERTIBLE CAR SEATS OF 2021 for you to – to save you some time, and stress, trying to find the best seat! I’ve outlined the best features of each seat so that you can make the best choice for you and your family.

CAR SEAT TIP: Before upgrading your child to the next seat up, or switching from rear to forward facing, make sure they’ve outgrown their current seat/position. Rear-facing until at least age 2 is HIGHLY recommended.

What are the Different Types of Car Seats?

The main types of car seats for your child, in the order you’ll need them, are the Infant Car seat, followed by the Convertible car seat, the 5-point Combination Harness-to-Booster and finally a Belt-Positioning Booster seat. More recently though, the All-in-One car seat has taken over the baby gear world as it is the ONLY car seat you will ever need! For a full comparison between all the types of car seats available to you, see our blog link following this article.
