Infant Car Seat vs. Convertible Car Seat: What’s the Difference?

Confused about what’s what in the world of car seats? We don’t blame you. Here’s the breakdown.

An infant car seat can only be used rear-facing and has a more limited height and weight range (often maxing out at 40 pounds). A convertible car seat, on the other hand, can be used both rear- and forward-facing, often from infancy to toddlerhood and beyond (depending on its height and weight capacity).

Another key difference between the two types of car seats? Infant options typically cannot be used after a child turns one, while convertible designs might last until a child is 4 or older. Infant car seats do offer parents more portability, since they’re lighter, can be clicked in and out of their base and often connect to stroller systems. In contrast, convertible car seats remain in the car. They can be a one-and-done purchase though, as they’ll grow with your child from their newborn days on.

When to Switch From Infant Car Seat to Convertible Car Seat

If you decide to use an infant car seat first, you’ll eventually have to switch over to a convertible car seat. Exactly when that happens depends on the size of your little one. As soon as they reach the maximum height and weight for your specific infant model, it’s time to make the move to a rear-facing convertible design But even if your child stays within the infant car seat’s size limits by their first birthday, you should consider making the move over to a convertible option for baby’s safety. Consumer Reports finds that a convertible car seat is safer in a crash than an infant car seat for children one and older.

What to Look for When Shopping for a Top-Rated Convertible Car Seat

Need help finding a top-rated convertible car seat for your little one? Below, find a list of questions that will help you spot key features and determine the best convertible car seat for your family:

  • How big is it? Convertible car seats are not known for being particularly slim and trim. Be sure to take into consideration the car seat’s width (especially if you have a smaller car or plan on having more than one car seat in the row) and also its length (particularly if the seat will be on the driver’s side). Take weight into consideration if you plan on switching the car seat from vehicle to vehicle or traveling with it.

  • What are its size limits? Many convertible car seats can hold infants as small as 4 pounds up to kids as large as 120 pounds—and anywhere in between. If you plan on using the seat from infancy on, make sure the weight limit starts low enough; on the flip side, if you want the seat to last beyond toddlerhood, look for a high weight and height capacity.

  • How does it install? Convertible car seats can be installed using either a car’s seat belt or a LATCH system (lower anchors and tethers for children), according to the American Academy of Pediatrics (AAP). While nearly all vehicles made after 2002 are equipped to use LATCH, it’s important to confirm before selecting a car seat. Also, correct installation is critical to a car seat’s safety—so look for a seat that makes the process simple.

  • What are its safety features? The good news: Except for any recalls (we’ll get into that in a bit), all convertible car seats available for purchase in the US will be safe to use (they must adhere to strict standards). However, there are some extra features that can increase a seat’s safety in the event of a crash or collision. Keep an eye out for some form of side-impact protection, through an adjustable headrest, side wings or energy-absorbing foam, and anti-rebound bars (ARB), which reduce the movement of the car seat towards the back of the car.

  • How comfortable will it be? Lots of features can make for an extra comfy ride for your little one. If planning to use the convertible car seat from infancy on, look for a seat that comes with an added infant insert for extra head and neck support. Moreover, multiple recline and headrest positions will tailor the ride for baby, cup holders will become critical as your child grows and an adjustable, no-rethread harness will make things easier for both parents and little ones alike. Another biggie: Examine the car seat for how easy it is to clean (because, hello, toddlers are messy).

Above all else, parents are looking for the safest convertible car seat possible. One way to determine that is through the National Highway Traffic Safety Administration’s (NHSTA) evaluations: The NHSTA evaluates convertible car seats for their ease of use, looking at four different categories and subsequently ranking them from one to five stars. And while the ranking doesn’t explicitly address safety, a car seat is only safe when used and installed correctly (which is where ease-of-use comes in). Additionally, the NHSTA keeps track of any car seat recalls.
