A buying guide


Your child is the most precious cargo that you will ever put into you vehicle. While there are a lot of different options available when it comes to choosing car seats, your best bet is to choose one of the highest rated convertible car seats.

The convertible car seats are designed to be used for newborns all the way to young children—once they hit a specific weight or height. While we cannot tell you what is the best convertible car seat, we can give you some of the key features that you need to take into consideration.



Safety Features

Safety is paramount when it comes to transporting your child in a car seat. You want to make sure the car seat uses a protective foam that distributes energy from an accident throughout the car seat, thus protecting your child from harm. Also, look for a car seat that uses a five point harness system and also features foam supports around the head.


Weight Limits

Typically, convertible car seats used to come in a standard weight limit, however, if you look at the top ten car seats, you will notice that the weight limits fluctuate from manufacturer to manufacturer. While it doesn’t determine which car seat you should buy, you will want to familiarize yourself with the maximum weight each model can accommodate. The highest weight limit for a rear-facing mode is usually 40 pounds, but you can find some capping at 30 pounds. For the front facing mode, you can typically find limits between 55 pounds to as high as 65 pounds. In terms of safety—always go with the highest number.


Vehicle Fit

While you may be drawn to one of the best rated convertible car seats because of the design or the color, if it will not fit in your car or does not fit properly, you are putting your child in harm’s way. If you have a small car, you will not want a tall shelled car seat because it will be troublesome when it is in the rear-facing mode. Also, the angle that the car’s rear seat can be a problem for some car seat bases. If you have other passengers, you will want to keep in mind the overall size of the car seat. While keeping your baby safe is top priority, the other passengers shouldn’t have to suffer due to being uncomfortable.


A convertible car seat is a necessity, but choosing one of the top ten car seats isn’t something that you should dread doing. With a little bit of research, we are confident that you will make the best decision for your family.
