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 the first year of their twins 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 RXT All-In-One Convertible Car Seat

The Diono Radian RXT All-In-One 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 forty-five pounds and then transitions to a forward-facing car seat for toddlers twenty to sixty-five pounds. When your twins are big kids, the Diono will not disappoint as a booster seat for your kids from fifty to one 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.


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 infant car seat to a booster seat with your twins, I think it is worth the investment.

Chicco KeyFit 30 Infant Car Seat

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.

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.

Graco Snugride 35 LX Infant Car Seat

The Graco Snugride35 LX Click Connect Infant Car Seat made our list for many reasons. There are several SnugRide infant car seat models made by Graco and this one is the higher end “Click Connect” model that is compatible with other Graco Click Connect strollers.

Why I Love It

The Snugride 35 LX is one of our favorites for the best car seats for twins for several reasons. Since you will be strapping in and taking out two babies, it is very convenient that this seat comes with a no re-thread adjustable harness which means you will not have to rethread the car seats manually. You will also like that you can adjust the harness height with fifteen different height positions as your twins grow taller. One of the main reasons I like this seat for twins is the lower body positioning insert for preemies and smaller babies.


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

UPPAbaby MESA Infant Car Seat

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.

This is a great choice for a best car seat for small cars, too.

Evenflo Embrace Select Infant Car Seat

The Evenflo Embrace Select 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 Embrace infant car seat. I LOVE the very reasonable price point and that it safely fits infants and babies from four to thirty-five pounds offering secure and safe premium protection for normal and low birth-weight babies. In fact, it is nationally recognized as a good car seat for low birth-weight babies, as well as a best car seat for twins.

A few notable features in this seat for your twins are the removable head pillow, a substantial canopy with full coverage, and a well-designed ergonomic handle. I also like that it this seat is very lightweight at under 8lbs which is extra important parents of twins.


Some experienced moms noted that if the car seat is not put in at the correct angle, the back of the seat will click in the back but not in the front. Be sure that both sides are secured when putting this seat into your car. This is inconvenient and potentially a problem if you’re unaware of the problem. This does not have to be a deal breaker so be diligent about checking that the car seat is securely and properly in the base.

Britax Boulevard Convertible Car Seat

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.

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

Why I Love It

The thing I love about all Britax car seats is the 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 icicing 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 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!

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 to check 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 the 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!
