7 Best Portable Car Seats for Babies, Toddlers and Big Kids

The Doona car seat is our pick for the best overall car seat and stroller combo and it's one of our past Parenting Award winners. A dedicated fan following backs it up; see its more than 13,000 five-star reviews on Amazon. The Doona makes it easy to switch between car seat and stroller mode in seconds even with your baby strapped inside. In short, you don't need a separate infant car seat and a stroller, because this is both.

"It's the easiest stroller to maneuver through airport security and around an airport terminal," says one tester who's a mom of two young kids. It goes into a rideshare vehicle using the seat belt (no stroller to put in the trunk!). It's also FAA-approved for use in an airplane cabin and fits on most economy airplane seats, which are often about 17 inches wide.

Rachel Rothman, the Good Housekeeping Institute's former Chief Technologist and a mom of three, is a fan of this for travel. But it's important to note that, as well as being pricey, the Doona is only for rear-facing use and for toddlers up to 35 pounds. Toddlers outgrow it typically at age 2. But if you'll travel a lot in those first two years — even if it's just catching Ubers around town — you'll be grateful for the Doona.

Big kids need a bit of help ensuring that the seatbelt is hitting their body just right, so this backless booster gives them that extra height. It's also exceptionally small, lightweight and easy to travel with; you might even keep several in your car's trunk for when you're carpooling other kids.

Because it's backless, it doesn't offer as much support as a highback booster (for that, see the Peg Perego on this list). It is okayed for ages 4 and up as long as they weigh at least 40 pounds and could be great for a quick trip when you don't want to lug something large. This fits into a tote bag!

With its two hideaway cupholders, machine-washable seat cushions and padded armrests, this tucks a lot of features into a (really!) affordable seat. It's no surprise that it has more than 20,000 five-star reviews on Amazon. While it isn't airline approved — all booster seats require a shoulder belt, which you won't find on an airplane — its compact size makes it incredibly simple to slide into your overhead bin to later use in taxis, Ubers or other vehicles once you get to your destination.

For a little more money there's a TurboBooster LX version that works with LATCH; nice if you'll be keeping this in one car for a length of time.

Got enough to carry already? At 10 pounds, this is the best lightweight convertible car seat for traveling and it won't break the bank. Five harness heights and three buckle locations help customize the seat to your baby or toddler's size, though it's the kind of harness you have to rethread each time you need to change it.

The Scenera can be installed rear-facing for babies and toddlers and forward-facing for preschoolers up to 40 pounds but lacks the cushioning and other comforts, like a recline mechanism, we've come to enjoy in an everyday toddler car seat. Still, with its deep bucket seat, this will keep your tiny passenger comfy enough and car seat compliant when you're traveling and in and out of other people's vehicles. It's especially great as a rear-facing travel option for 2- and 3-year-olds who have outgrown an infant car seat.

You can remove both the cupholder and seat pad for washing. The seat pad can even go in the dryer. The brand claims that three of these seats fit across a back seat and our tests were able to validate that in certain vehicles. It can be installed with the LATCH system or a seatbelt. It's approved for airplane seats and like our best overall pick it fits on most economy seats.

Kids who are at least age 4 and who weigh 40 pounds or more will appreciate the comfort of this belt-positioning booster seat just as much as parents will appreciate its ability to fold down to a fraction of its size.

The Flex 120 has an exceptionally large weight range, functioning for kids up to — you guessed it — 120 pounds. While it's a bit pricier than some other booster options, its ability to compact down makes it perfect for folding up and storing in a bag that you can then gate-check, or even fit into the overhead bin while in-flight. Note that no belt-positioning booster is certified for use in an airplane cabin because they're meant to be used with a car's shoulder belt, not an airplane lap belt. The big kids who fit this are good to use the airplane belt anyway! This is perfect for use in a rideshare, taxi or a far-off relative's vehicle when you land.

Customize this booster to your child by adjusting the headrest, upper backrest, side wings and seat. In addition to being an easy portable car seat, this is another great choice for grandparents or other caregivers who only occasionally drive big kids around because it so easily fits into a car's trunk when not in use.

This is larger and heavier than any of our other choices. However, this is the most portable all-in-one car seat that grows with your little one from a rear-facing infant car seat to a backless booster, from 4 to 120 pounds.

Its versatility means that it may be the only car seat you ever have to buy, and if you travel infrequently, you could manage to tote this on a few trips and avoid buying something separate just for travel. It is certified to work on an airplane seat with the harness (so, up to 65 pounds), but it's about 3 inches wider than many economy airplane seats so the fit isn't great; one Reddit user said they put it in the window seat and then just accepted squeezing themselves into the middle-seat position.

While testing, we appreciated how easy this car seat was to install and use, making it pretty difficult to mess up due to user error. We also love how highly adjustable it is, with a six-position recline and a no-rethread harness with 10 possible heights. The easy-to-remove washable seat pads make it simple to clean up after your little one. If you're taking it with you into a rideshare and can't use the LATCH installation system, there's an integrated belt lock off on the back of the seat that helps make seat belt installation as simple as possible.

This is a pricey option that has a fan following with frequent travelers who travel with a preschooler. It folds down into its own carrying case, which can be worn as a backpack, so you can easily get it through the airport and store it in a hotel. It's got a five-point harness and is meant for kids up to 50 pounds. The brand says it's for kids as young as 2 but because rear-facing is safest and this only faces forward, we would not recommend using it for a child until they are at least age 3, preferably 4.

The Pico does not have side-impact protection and other safety features we want on an everyday car seat, but for travel we agree that this has portability appeal. It also gets knocked in reviews for not being comfortable for long car rides if your child likes to nap, but again, we're putting it on this list for on-the-go families who are in "something is better than nothing" mode, even for short train, bus or van rides.

Our experts appreciate how lightweight this seat is (8 pounds), and that it easily fits even on the smallest economy airplane seat (it's FAA-approved). The seat can either be installed using the LATCH system or the seatbelt in a car or airplane.

If you're a city family that doesn't even own a car, there's a big reason to love the PIPA portable infant car seat: It's built to be installed without a base and is exceptionally easy to move between vehicles, including rideshares like Uber.

It's got a built-in rigid LATCH system or alternatively you can use the back seat seatbelt. Plus, the PIPA urbn only weighs 7 pounds, making it one of the lightest infant car seats we know of and an easy one to carry from place to place. The stroller, too, is lightweight at just under 14 pounds and can be folded down using just one hand. The car seat is built to ride on top of the stroller, to get them both through an airport, and we named it our favorite lightweight travel system.

The infant car seat does not have a high weight limit, however. Your baby will outgrow it when they hit 22 pounds or are 29 inches tall, whichever comes first. For some that can mean by their first birthday. But the stroller will stay useful through the preschool years since it has a weight limit of 50 pounds. The car seat is airline-approved and will fit on most economy cabin seats.
