There are a lot of factors to consider when it comes to your baby’s safety, but few are as crucial as your child’s car seat. Too many children have lost their lives or suffered grave injuries from improper car seat use, so it is very important that you select the right car seat and install it correctly.

Finding a good convertible car seat can save you money and give you peace of mind knowing that your baby is safe.

Benefits of a Convertible Car Seat

Your child’s seating situation in your vehicle will change many times over the next several years, transitioning from arear facing seat to front facing, then to a belt-positioning booster seat before they are eventually able to sit in the seat with the belt alone.

This can create a lot of wear on a parent’s wallet, especially when you are buying a different seat for each stage. Starting with a convertible car seat can save you money in the long run if you know what you are looking for.

Many convertible car seats can be used in all three positions, taking your child from infancy through early childhood. They are clearly labeled with height and weight limitations so you know what will work best for your child.

Recommendations from the AAP:

Be sure you always check for any updates from the American Academy of Pediatrics (AAP) regarding car seat safety.

  • Rear Facing – until the child reaches the height and weight limits of the rear-facing car seat, usually by age 2 or later.
  • Front Facing – until the child reaches the height and weight limits of the front facing car seat, usually up to 65 pounds; they will transition to a belt-positioning booster at this point.
  • Expiration Date – each car seat has an expiration date, usually 6 years from the manufacture date.
  • Second Hand or Used – don’t purchase used or second hand if you don’t know the car seat’s history or if the car seat has been involved in a crash (even a fender bender).

You can use this car seat both rear and forward facing; as a bonus, you can also use it as a seat belt positioning booster seat. This means you can use the car seat from birth right on through 120 pounds.

Another premium convertible car seat on our list is the Clek Foonf.

4. Britax Boulevard CT ARB 

Britax is known for their top-rated strollers (like the Beast of Burden [BOB]), so it goes without saying that their car seats are also worth noting.

The Britax Boulevard CT ARB is built to keep your baby safe. With a steel frame and two layers of side impact protection, there is little you need to fear in the event of an accident. The ARB part of the car seat is also worth noting; there is an additional anti-rebound bar that provides additional safety with installed rear facing.

Car seats are notoriously messy, so Britax has fitted theirs with Nanotex fabric technology. This makes the lining resistant to stains, moisture, and odor to keep the car seat in good condition while keeping your baby comfortable.

  • The anti-rebound bar for additional safety
  • Can be used from birth
  • Built to last

5. Nuna RAVA

Most car seats are notorious for being too big. They take up a lot of space in the back seat and can reduce leg room for front seat riders, particularly when the car seat is installed rear facing. With the recommendations that children should ride rear-facing past age two, your long-legged child may also be short on leg room.

The Nuna RAVA gives your child more leg room when installed both rear and front facing. You can also ensure your child is comfortable thanks to the 10-position recline at the base.

There is no LATCH system for this car seat, but Nuna believes that belt is best. It adapts to more car styles and creates a unique, always tight fit with the lock-off doors. It is also easier to install and ensure a tight fit than with the LATCH system.


  • Easy to install with the seat belt
  • No re-thread harness
  • Extra leg room rear and forward facing
  • 10-position recline
  • Breathable fabric


  • No booster option
  • Very heavy
  • Expensive

If I had to choose one convertible car seat overall, I would have to say the Diono Radiant RXT is my top choice. It may be a bit expensive to pay for at first, but for the amount of life and use you will get out of it, it will more than pay for itself.
