Best Car Seats for Twins

Having two babies at once is such an amazing gift but also requires so much from new parents. 

WebMD estimates that parents will spend approximately $1500 on clothes and diapers in the first year of their twin’s lives. In my research, I read that you will likely go through 140 or more diapers a week with a set of newborn twins.

In addition to the emotional and physical changes, it clearly can also put a hefty dent in your wallet with two car seats, two cribs, two sets of clothes and so much more.

We hope to help you feel prepared to bring your two bundles of joy home from the hospital. We have compiled a list of what we believe are the best car seats for twins. After interviewing experienced twin moms and researching many options, these are the ones that made our final cut.

I hope our research and list of the best car seats for twins help make the transition easier for your growing family as you welcome your babies home.

The Best Car Seats for Twins

Diono Radian 2021 3RXT 4-in-1 Convertible Car Seat

Diono 2021 Radian 3RXT, 4-in-1 Convertible, Extended Rear Facing, 10 Years 1 Car Seat, Fits 3 Across, Slim Fit Design, Gray Slate

The Diono Radian 2021 3RXT 4-in-1 Convertible Car Seat is our top pick for the best car seats for twins.

Why I Love It

While being secure and safe for your twin babies, the Diono is also compact and narrow enough to fit three across in most mid-size vehicles. This is particularly helpful if in addition to your precious twins you have a toddler or older child that still requires a car seat.

Another reason to love this twin car seat is that it can change as they grow. It is made for babies in the rear-facing position from five pounds to fifty pounds and then transitions to a forward-facing car seat for toddlers twenty-two pounds to sixty-five pounds. When your twins are big kids, the Diono will not disappoint as a booster seat for your kids from 40 pounds to one hundred and twenty pounds. My twin mom friends love this one!

Even though you are looking specifically for twin car seats it is a good idea to review Experienced Mommy’s reviews of the best car seats in general since there may be a car seat that is better overall, even if it isn’t intentionally designed for cars with multiple kids. Choose from five different colors: Gray Slate, Black Jet, Blue Sky, Purple Plum, or Red Cherry.


Since you will need to buy two of the Diono’s, one drawback is the higher price point. Personally, since this car seat transitions from an infant car seat to a booster seat with your twins, I think it is worth the investment.

Chicco KeyFit 30 Infant Car Seat

Chicco KeyFit 30 Infant Car Seat, Orion

The Chicco KeyFit 30 Infant Car Seat is well liked by doctors, nurses, and hospitals because it fits preemies and small babies so well which is great for families with twins. Often times twin babies weigh slightly less than singleton births and are born earlier than their due dates. So, a car seat that is designed for smaller and lighter babies is a great fit for a mom with twins.

If you want more information or ideas for preemie car seats, read our full review article for preemie car seats.

Why I Love It

The Chicco KeyFit 30 is a quick runner-up to the Diono. In addition to being a hospital favorite, it is also reasonably priced which will help your family since you will need to buy two of them for your twins.  You will also need to purchase a stroller that will carry two car seats and this model of the Chicco car seat is compatible with almost every twin stroller on the market.

It was also voted top-rated by Consumer Reports because this twin car seat excelled in their new crash protocol and also because it is one of the easiest seats to install using either your vehicle’s LATCH system or the safety belts.

A few other helpful features are the compact size and narrow shape.


Your twins’ height may outgrow these twin car seats before the weight restrictions are met but honestly, this happens with many rear-facing infant seats.

Britax Boulevard Convertible Car Seat

Britax Boulevard ClickTight Convertible Car Seat | 2 Layer Impact Protection - Rear & Forward Facing - 5 to 65 Pounds, Circa

We talked about how expensive twins can be, so one way to save money, in the long run, is to buy a convertible car seat. That way, you won’t need to buy an infant seat, plus a forward-facing seat later on. And when it comes to safe, comfortable, and easy-to-use twin car seats, look no further than the Britax Boulevard with ClickTight.

Why I Love It

The thing I love about all Britax car seats is safety. This convertible car seat has the SafeCell impact-absorbing base, just like their infant car seats do. It also has a v-shaped top tether for more security, since it has two points of contact instead of just one. It also has a steel frame and two layers of side impact protection.

You also can’t beat the ClickTight securing system. You just lift up the panel under the seat, buckle the vehicle belt along the seat belt path, and click the panel back down. It’s guaranteed to get you a great and secure fit! If you want, you can use the latch belts.

This car seat for twins also has 7 recline positions, 14 headrest positions, and a quick-adjust headrest that adjusts the harness and headrest all in one go. The harness is easy to tighten and gives you a loud click when it’s tight enough. And, the icing on the cake is that it’s only 18.5 inches wide, so you can definitely get 2 or even 3 across in one car. You can’t beat all those great safe and user-friendly features!


Probably the biggest drawback here is the price. This is one of the most expensive convertible car seats, but when you have 5-star safety and user ratings, you get what you pay for!

If you are wondering if the slightly cheaper Britax Marathon is just as good, read our Marathon vs Boulevard comparison article.

UPPAbaby MESA Infant Car Seat

2018 UPPAbaby MESA Infant Car Seat - Jake (Black)

The UPPAbaby MESA Infant Car Seat won the five-star rating from National Highway Traffic Safety Administration.

Why I Love It

The UPPAbaby Mesa is a luxury version of the infant car seat.  It comes with the no re-thread harness with five different harness height positions and two buckle positions. One of the top perks of this twin car seat is the ease of installation because of the Mesa’s adjustable base with a tension indicator and self-ratcheting lower LATCH connectors.

Several notable features are the sleek design, high-end fabrics, and substantial canopy.


UPPAbaby is a well-known luxury brand which means luxury prices which is something to weigh when you need to buy two of everything. Many moms would argue that the Mesa is completely worth the money.

There are the best car seats for small cars, too.

Graco SnugRide SnugLock 35 Platinum Infant Car Seat

Graco SnugRide SnugLock 35 Platinum Infant Car Seat | Baby Car Seat, Spencer

The Graco SnugRide SnugLock 35 Platinum Infant Car Seat made our list for many reasons. There are several SnugRide infant car seat models made by Graco and this one is a popular choice with SnugLock Easy Install and premium comfort. Newborn twins can ride in the SnugRide up to 35 pounds and 32″. 

Why I Love It

The SnugRide SnugLock 35 is one of our favorites for the best car seats for twins for several reasons. The SnugLock feature is a wonderful feature because it allows you to easily install each car seat with a hassle-free 3-step installation using the seatbelt or LATCH system. Also, a Simply Safe Adjust Harness System, that adjusts the harness height and headrest at the same time, allows your child to ride safely and comfortably. Finally, you can adjust the handle with just one hand! This is exceptionally helpful when you’re going to need both hands with two babies.


The Snugride SnugLock 35 is a bit bulkier than some infant car seats and can take up a fair amount of space in your back seat. Keep this in mind if you have a smaller vehicle or a compact car.

Check out our narrow car seat reviews for better options for smaller vehicles.

Evenflo LiteMax 35 Infant Car Seat

Evenflo LiteMax 35 Infant Car Seat, Easy to Install, Versatile & Convenient, Meets or Exceeds All Federal Safety Standards, Machine-Washable Pads, Full-Coverage Canopy, Riverstone Gray

The Evenflo LiteMax 35 Infant Car Seat is a great budget-friendly option with some notable features.

Why I Love It

There are quite a few reasons you will love the Evenflo LiteMax infant car seat. I LOVE the very reasonable price point and that it safely fits infants and babies from four to thirty-five pounds and 17 to 32 inches tall, offering secure and safe premium protection for normal and low birth-weight babies. 

A few notable features in this seat for your twins are the removable head pillow, a substantial canopy with full coverage, and 4 harness position options. Moms say this car seat is lightweight too which is great for parents with twins.


Some experienced moms noted that their chunkier baby outgrew this car seat very quickly because the baby seemed squished. This may be something to consider if you have an idea of your baby’s size.

FAQ’s about Best Car Seats for Twins

When should I purchase the car seats for my babies?

I would suggest getting the twin car seats ahead of time for two main reasons. One reason is so that you can become familiar with properly and securely placing them in your vehicle.

Secondly, you must have a car seat to bring your baby home and the hospital will require it for your baby to be discharged.

What is the Infant Car Seat Test and when is it necessary?

Twins can often be born prior to their due date. Infants born earlier than thirty-seven weeks will be required to pass the car seat test in order to be discharged. 

The Experts at the Children’s Hospital of Philadelphia explain,

“Car seat testing is usually done in the hospital within one week before your baby is ready to go home. You will be asked to bring in your baby’s car seat, which he will sit in for 90 to 120 minutes or the length of the car ride home, whichever is longer. During the test, the nurse will monitor your baby’s heart rate, breathing, and oxygen level.  If your baby passes the car seat test, he will be able to use the car seat you have provided. If not, the hospital may repeat the same car seat test.”

Where can I learn safety facts about choosing the best car seats for twins?

I would suggest looking at the National Highway Traffic Safety Administration for safety guides for car seats and checking this site regularly for recalls even after selecting your favorite car seat for your twins.

Final Recommendation for the Best Car Seats for Twins

Overall, each of our choices for the best car seats for twins is a winner. Each of them has great benefits and meet or exceed national safety standards. 

In the end, my overall favorite and winner is the Diono. It made the top of our list mainly because it is compact enough to fit three across in most mid-size vehicles and because it will convert as your twins grow from infancy to big kid status. Remember, my twin mom friends highly recommend this one!
