3 Across Installations: Which Car Seats Fit a Chrysler 300?

The Chrysler 300 is one of the most sought-after large sedans available today in the United States, and it’s easy to see why. It competes strongly with the Ford Taurus, Toyota Avalon, Chevrolet Impala, Buick Lacrosse, and its Dodge twin the Dodge Charger as a family vehicle with plenty of room, plenty of power, and plenty of style. The newest versions of the 300 include a range of up-to-date safety features, including a good moderate overlap score, a good side impact and roof score, and ESC, which is finally a requirement in all new US-spec cars.

I borrowed a current and previous generation 300 to see if it worked just as well as its Charger twin when it came to puzzling 3 car seats across the back seats. The good news is that yes, it does a great job, and is still one of the most car seat-friendly cars I’ve come across. Before looking into the details, however, it’s worth reviewing when it’s a good idea to use infant and convertible seats, forward-facing and combination seats, booster seats, and the adult seat belt to keep our kids safe.

First of all, start with rear-facing. That goes for infants, toddlers (here are some tips to make rear-facing with them more bearable), and even preschoolers. The longer you can rear-face (aim for 4!), the better. That can be done with infant and convertible seats. Next, you’ll want to forward-face your little ones in harnessed convertible or combination seats (ideally until 8!). Once they outgrow their harnessed seats, I suggest keeping them in high-back boosters until they’re physically and psychologically ready to use adult seat belt systems (which typically happens between 10 and 12). The goal is to use the safest seats for as long as possible to keep your kids as safe as possible.

With this in mind, I tested a range of seats to figure out which car seats work best in 3 across setups in the Chrysler 300. It’s my goal to make lists like these the most comprehensive on the Internet. If you find the list helpful when shopping for car seats, you can shop through my Amazon link below. I’ll add more seats as I test them over time.

Tips and Tricks:

The current generation of the Chrysler 300 is 199 inches long and 75 inches wide, which is about as good as it gets in most cars. Due to the length and width, you’ve got ample room both in terms of front-to-back space and in side-to-side space. That said, it can still feel a bit cramped when using particularly wide seats like the Britax ClickTight series, so you’ll want to use your seat belts instead of the LATCH anchors to take full advantage of the space.

Tips and Tricks:

The initial modern generation of the Chrysler 300 is 198 inches long and 74 inches wide, or 1 inch shorter and 1 inch narrower than the current generation. That said, it’s still similar in size to other large family sedans on the market, and you’re likely to be able to get a wide range of car seats in it successfully in 3 across configurations. As always, choose seat belts over LATCH to maximize side-to-side space.
