Varieties of Car Seats

When deciding when to switch from an infant to a convertible car seat, a little bit of research can go a long way.

Infant Car Seats vs. Convertible Seats

Infant car seats: Infant car seats, also known as bucket seats, are designed for newborns and younger children riding in cars. A child can use an infant seat from birth until he or she reaches the maximum height or weight allowed for the seat, which is typically around one year of age. The bases of infant car seats are designed to stay in your vehicle and can be easily clicked in and out.


Convertible car seats: Children of varying ages and sizes can ride safely in convertible car seats. Convertible car seats have a rear-facing mode and a forward-facing mode for when your child outgrows the rear-facing limits of the seat. Unlike infant car seats, which require a separate base for installation, convertible car seats can be secured in your vehicle with the vehicle's seat belt or the LATCH system. The Lower Anchor and Tethers for Children (LATCH) system consists of a car seat's built-in straps and hooks and the anchor hardware in your vehicle. With LATCH, installing a child safety seat in a vehicle is quick and easy. Because of their bulk and weight, convertible seats aren't ideal for frequent swapping between vehicles.

How Long Do Infant Seats Last?

It's important to stay informed about how long infant seats are good for. As your baby grows, you'll need to know when it's time to upgrade to a bigger seat that will safely accommodate their increased size and weight. While most infant seats have a weight limit of around 30-35 pounds, it's the height limitations that you want to keep an eye on. Once your baby's head is level with the top of the seat, it's time to trade up to a new rear-facing car seat. But remember, each car seat has its own specific requirements, so consult the guidelines before making any changes. Your baby's safety is always the top priority.

When to Switch from Infant Car Seat to Convertible

A question for many parents is when to transition their baby from an infant car seat to a convertible car seat. The answer lies in the height and weight restrictions of the infant seat. It's important to note that your child can stay in their infant seat until they outgrow it by either height or weight. While the weight limit is important, most children will outgrow their infant seats due to height long before they reach the limit. If the top of your baby's head is within one inch of the top of the shell of the seat, then it's time to transition. Safety never takes a backseat when it comes to your baby, and a convertible car seat will provide your child with the proper protection as they grow.

Choosing the Best Convertible Car Seat

So, you've decided to upgrade your child's car seat from an infant to a convertible model; what comes next? You should start by researching different convertible car seats to see which one works best for your child and your vehicle. Some things to think about are as follows:


  • Safety: The safest car seat is the one that is the right size for your child, will fit in your car, and can be installed properly each and every time, as required by U.S. law. Additional shock absorption, an anti-rebound bar, side-impact protection, and a stability/load leg are all safety extras to look out for.
  • Quick and simple set up: The seat belt or the LATCH system in your car may be all that's needed to install many different types of car seats. (LATCH saves time.) Be aware of the LATCH weight limits for your seat and switch to a seat belt install if you or your child are going to exceed them.
  • Fit: The sizes and shapes of cars and car seats are both diverse. Make sure there's enough space for the driver and other passengers in the front and back of the car with the seat you choose, and that it can be installed properly in your vehicle.
  • Rear-facing weight limit. More and more studies show that rear-facing car seats are safer for infants and young children than their forward-facing counterparts. Choose a convertible car seat with a high rear-facing weight limit if possible, so that your child can ride in that position for as long as possible.
  • Fabric: Think about how long the fabric will last and if it can be easily cleaned.
  • Brand-new versus previously-owned: When possible, always buy a brand-new car seat. Get a used car seat from someone you know and trust, and inspect it carefully to make sure it hasn't been damaged in an accident. Check the seat's expiration date and see if there have been any recalls on that specific model. When cleaning, make sure to strictly adhere to the guidelines provided by the manufacturer.
