If you have a baby and you have a car, you need a car seat — that much is a given. What kind, style and model, however, there is a world full of options of that can be overwhelming at times as you try to figure out which ones work at which stages and when it’s time to get a new one. One breed of car seat that makes things a bit easier is the convertible car seat.

Typically used after the infant car seat (though it can be used as an infant car seat, but it is not removable from the base) these seats are typically meant to last through several stages, from rear-facing to forward facing and beyond. This is generally the car seat you will use for the longest amount of time, so finding one that is easy to clean, comfortable and has lots of positions to suit your little one are important. Here are eight of the best convertible car seats on the market.

Our Top Picks

How We Tested

Our reviewers spent 10 hours testing one of the top-rated convertible car seats available. To ensure the most complete feedback, they set it up in their cars and had their own children try it out for themselves. We asked our testers to consider the most important features when using this convertible car seat — from comfort to durability — and we've outlined the key points here so that you, too, know what to look for when shopping.

What to Look for in a Convertible Car Seat

Longevity: While convertible car seats are generally meant to last through several stages of your baby’s growth, some are more versatile than others. For example, there are models that work from a child’s infancy until they weigh about 120 pounds, while others have narrower weight ranges (like 20-65 pounds). Beyond height and weight limits, pay attention to adjustable features, like the number of harness positions, so that a seat is comfortable over time.

Ease of use: There are two main things to consider when it comes to a car seat’s ease of use: getting your child in and out of it and getting it in and out of your vehicle. Look at factors like its harness, the shape of its seat, and how it’s secured in your car. If you plan to use your car seat frequently, little time-saving features can add up to major headache relief over time.

Comfort: Some car seats are cushier with cup holders, lots of padding, and other features that make for a more comfortable ride. Of course, those extras usually increase the cost, so consider your budget as well as how often you’ll be using your car seat. If you’ll use it daily, spending more on a model with fancy features may be worth it.

One of our testers — who used this car seat with her 2-year-old son in her Toyota Avalon — said that strapping him in was “easier than other models we’ve tried.” She added, “He was very happy in this!” Other highlights were the seat’s attractive design and the fact you can use it in four different configurations as your child grows.

Our testers wished this seat had a foot extender (for taller children) and that the instructions were a little less technical: “I wish they had more basic-level stuff like when to use certain versions of the car seat at certain times,” said one reviewer.
