Chicco KeyFit – #1 Infant Car Seat Review – Pros & Cons

Chicco Keyfit Infant Car Seat and Base with Car Seat, Color: Lilla

In 1958, Pietro Catelli, an Italian inventor of medical devices, founded Chicco after his first son was born. Chicco has grown since then to 120 countries and offers gear for all things baby, including toys, nursing products, clothes, shoes, and more.

Chicco still honors their Italian heritage with a focus on quality and style. Their headquarters aren’t far from Milan, which of course is the world’s fashion capital. Chicco’s fashion experts travel far and wide to search for all the new trends in baby products, with a focus on safety, comfort, and style trends. They believe chic and functional go hand in hand.

The Chicco Keyfit Infant Car Seat with Base fits the bill with both style and function. We’ve compared it to other products on the market, and while it has a few flaws, we think it’s a great choice for your baby. If you’re getting ready to welcome a little one into the world, or if you’re simply looking for an extra car seat or an alternative, here’s why you should consider this car seat.

Why choose an infant seat and not a convertible (all-in-one) seat?

With all the combo car seats out there, you may wonder why you should bother with a separate infant seat. The convertible seats can switch from forward to rear-facing until the child is about 40-80 pounds. An all-in-one seat can carry a child from infant until she no longer needs a booster. And they’re not terrible products by any means, but an infant seat is designed for just that – carrying infants.

Most safety experts believe that newborns 20 pounds and under are safest in a rear-facing infant seat. With a convertible seat, the harness straps could be so long, it’s impossible to get them tight enough for a small baby. The harness slots might be positioned too high as well – if they’re not at or slightly below her shoulders, they may not offer as much protection as with an infants seat.

Don’t forget the convenience factor. Infant seats tend to be lighter and smaller than all-in-one or convertible seats. They fit snugly in a base in your car, and can usually snap on a stroller so you won’t disturb her if she’s sleeping.

What makes the Chicco Keyfit different?

As one of the most popular infant car seats in the USA, the Chicco Keyfit has several things going for it.

Key features

  • 5-point harness
  • EPS foam to absorb impact in case of an accident
  • Easy-to-use buckle
  • Easy-to-attach LATCH connections
  • Easy-to-adjust LATCH strap
  • Bubble level on the base to ensure proper angle when installing
  • Can leave handle up while in vehicle
  • Machine-washable covers
  • Works with compatible strollers
  • Good fit for premature infants

Note the Chicco Keyfit can also be bought as a part of the Chicco Bravo stroller as a travel system. We rated it 9.6 out of 10 in our travel system reviews.

What are the size limits for the Chicco Keyfit?

  • 4-11 pounds with the newborn insert (included)
  • > 11 – 20 pounds without the newborn insert

Note that there is also a modified model called the KeyFit 30 Magic that has a higher weight limit (30 pounds) than the original (20 pounds). Be aware when ordering online that some colors are exclusive to the KeyFit 30 and vice versa.

How big is this seat, and will it work with your vehicle?

If you’re looking for a light, easy to transfer seat, you’re probably in good shape with this one. It won’t take up a ton of space in the backseat at only 17 inches wide, but for smaller, fuel-efficient cars, it could be a little big, especially if you need more car seats in the back.

  • Weight – 9.6 pounds – mid-range compared to others on the market
  • Dimensions – 17 x 27.5 x 24 inches
  • Harness slots with newborn insert: 7, 9, and 11 inches
  • Harness slots without newborn insert: 8, 10, and 12 inches.

Helpful tip: Purchase an extra base to store in a second vehicle for quick click and go transfers when you need to switch vehicles.

How safe is the Chicco Keyfit?

Crash test results have been excellent for this car seat. It ranked in the top 5 for crash testing compared to other top brands, and for head injuries, tested higher than federal safety standards. Energy absorbing foam and plenty of head and body support help protect even very small babies in case of a crash.

The SuperCinch LATCH

In fact, NICU nurses recommend the Keyfit because of the infant insert which provides an extra layer of protection for premature or small infants. The seat is also FAA compliant, so you can easily switch from ground to air and back again.

Several design features work toward the overall safety of the Keyfit. No two models of cars are the same, but the spring-loaded ReclineSure leveling system helps you adjust the fit in the varied back seat designs for a lot of different vehicles. Bubble levels on each side of the base help remove any doubts that you may have the seat at an improper angle. The SuperCinch LATCH tightener ensures a secure, tight fit in just a pull.

Possible flaws:

Some reviewers have had trouble getting the shoulder straps tight enough. Also, one reported that just hearing one click may not mean the car seat is securely in the base. This user had to press down harder until a louder click was heard. So be aware that you can’t depend on a click alone. We recommend you always pull up on the seat to make sure it’s nice and snug in the base before driving.

Other reviewers have found the fabric on the seat interior doesn’t breathe well enough, contributing to excess sweating. They’ve also found the canopy didn’t cover well, leaving the baby somewhat exposed to the sun. Be sure not to dress your child too warmly when riding and use car window shades and/or thin blankets to keep the sun off and avoid overheating. They have reported that the Keyfit 30 Magic has an improved canopy so it may not be an issue with that model.

How hard is it to install?

For parents of newborns, especially first-time parents, making sure the car seat is just right can be an added stress in an already stressful time of life. The overall design of the Chicco Keyfit is intended to help parents to correctly install the car seat the first time, every time.

When you hear a definite click, you know the seat is attached firmly to the base. If you use the bubble levels and ReclineSure system, you can rest assured that your baby’s seat is safe and secure, even if you’ve never installed a car seat before. Be sure to always refer to your owner’s manual for complete instructions on how to install. Baby product models are constantly changing, so the manual should be your first stop when installing.

If you have a pre-2000’s vehicle with no LATCH system, you can use the seat belt to secure the base.

Possible flaw:

While the KeyFit can be used without a base, installing it to the correct angle and tightness without the base has proved difficult for some users. You’ll need to use the red line on the sticker/label to help you find the right angle. Rolled-up towels may be used to help level it out.

Optional accessories

Like most baby travel products, a number of accessories can be used with the KeyFit to make baby’s trip (and yours) a little better. Here are a few you might want to try, a couple of which we’ve mentioned already:

  • Chicco Keyfit and Keyfit30 Infant Car Seat Base – Works for both the original and 30 model. Make sure you have at least two bases if you’re going to be transferring the car seat from one vehicle to another. It’ll save time and you won’t have to worry about correct installation of the base every time.
  • Chicco Bravo Trio Travel System – You’ll be wanting a stroller too unless you’re a complete hermit, so why not invest in a 3-for-1 package? This system features the Keyfit car seat and a sturdy stroller. Keep your baby asleep in her car seat while you snap it to the stroller’s frame. When she’s older, ditch the seat and let her ride in stroller style.
  • Chicco Keyfit Caddy Stroller Frame – If you already have the Keyfit car seat, you can opt for this stroller frame. Just click the car seat (with baby) on the frame and go. It folds up with one hand and fits nicely into your vehicle’s storage. The parent tray with cup holders and big storage basket make it perfect for a nice shopping trip or day at the park.
  • Skip Hop Baby Pronto Portable Changing Station – It never fails. You’re strolling along at the park, and oops, baby’s filled the diaper and there’s no changing room nearby. Take along this little travel changing station, and you’ll keep baby clean and dry everywhere you go. It holds up to 4 diapers with wipes and can clip on your wrist or your stroller. A zippered pocket holds your keys, wallet, phone, etc.
  • Baby Car Mirror for Back Seat  – Keep an eye on your rear-facing baby with this handy mirror. It goes right on your headrest with straps that keep it snug and secure. You can glance at your preemie or older baby and know if they’re in urgent need of care.

Best Car Seat Hub’s Final Verdict

Let’s review a few praises and criticisms for the Chicco Keyfit Infant car seat.

  • Quality – A top-rated infant seat from a well-known company
  • Secure fit – Good fit for preemies and very small babies that otherwise might not fit well in other models of car seats
  • Easy installation – Several features designed specifically for right the first time installation – bubble levels, adjustable recline angles and one-pull latch tightener
  • Compact – Sized for smaller vehicles, no mini-van needed
  • Easy cleaning – Removable, machine washable covers.
  • Travel-friendly – Conforms to FAA regulations; clicks on compatible strollers; relatively lightweight
  • Made in China – Most things are these days, but be aware of recalls, inspect all parts before use in case of damage or poor construction, and know the return policy of the seller
  • Not breathable – Fabric on interior may not be breathable enough; watch for overheating and excessive sweating, especially in hotter months.
  • Less sun protection – Canopy may not stretch far enough to cover baby for complete sun protection
  • Strap tightness – Some reports of difficulty tightening the straps
  • Weight – At 9.6 pounds, it may be challenging to carry a bigger baby around in it without the help of a stroller or baby carrier.
  • Not as secure without the base – Can be used without the base, but some users had a hard time getting it adjusted just right


While this seat isn’t perfect (none are), it has a lot of things going for it. For families with preemies that have a hard time finding the right-sized products, this car seat is your friend. From 4 – 20 lbs., it’ll keep baby snug and secure until she’s ready for an upgrade. The sister model, the Chicco Keyfit 30 Magic will hold up to 30 lbs. It’s performed very well in crash tests and has plenty of head support and side impact foam for protection in case of a crash. The best thing about it may be its easy installation, which would be great for new parents or caregivers that aren’t familiar with car seats. Having a second base is highly recommended if you’ll be switching vehicles often.

Before you buy, there are a few issues to take into consideration. It’s made in China, and while that doesn’t necessarily affect quality, shipping long distances can increase the likelihood of damage. Always inspect your car seat parts before use, and that goes for any car seat. If you’re worried about your baby overheating, or live in a hot climate, take note that the fabric may not breathe as well as other models and dress your baby accordingly. Plan for extra sun protection too with car window sun shades or thin blankets since the canopy may not extend fully enough.

Overall, the Chicco Keyfit seems like a great starter car seat, especially if you have a preemie or newborn. Buying an extra base or as part of a travel system with a stroller will ensure more convenient travels for families always on the go. If you’re getting ready to have a baby, put this seat on your registry list.

    My 10 month old grand baby can unbuckle her Chicco Keyfit30 top harness by pushing the button. Beware how easy this is to unbuckle!

  2. Brit says:

    How does this compare to the newest chicco fit2?

    1. Emma Lachey says:

      Hi Brit, thanks for your question. The Chicco Fit2 has a few differences from the KeyFit30, namely weight limits.

      Weight limits:

      • KeyFit30 4 – 30 pounds
      • Fit2 4 – 35 pounds

      The Fit2 actually has 2 positions, including a toddler position from 15 – 35 pounds, whereas the KeyFit30 has only one. The Fit 2 also has a integrated stabilizer bar and a 7-position headrest that the KeyFit20 does not. It’s newer, therefore more expensive than the KeyFit30 as well.

      Both seats, however, are excellent.
