I have installed and used many car seats. The Chicco KeyFit 30 is a classic choice for new parents. The Chicco KeyFit 35 is its newer, bigger sibling. I used both for daily drives and long trips to see how they compare. This guide will help you choose the best one for your family.
Is Chicco KeyFit 30 Good?
The Chicco KeyFit 30 is America’s top-rated infant car seat for a good reason. When I took it out of the box, it felt solid and well-made. The materials are plastic and metal, which is standard. The fabric is durable and easy to clean. The carrier itself feels light, weighing only 9.5 lbs, making it easy to carry.
Installing the base was very simple. The instructions are clear. The bubble levels and spring-loaded foot help you get the right angle. The SuperCinch LATCH system makes it easy to get a tight, secure fit without a lot of effort. This is a big help for parents who worry about installation.
What I Like
- Super Easy Installation: The LATCH system and bubble levels make getting a safe install fast and simple.
- Lightweight Carrier: At 9.5 lbs, the carrier is not too heavy to carry from the car to the house or stroller.
- Proven Design: This seat has been trusted by parents for years. It does its job well without extra fuss.
- Stroller Compatibility: It clicks easily and securely into all compatible Chicco strollers.
- Good for Newborns: The included head and body support fits small babies from 4 lbs, giving them a snug and safe fit.
What Could Be Better
- Lower Height Limit: Babies can only use it up to 30 inches tall. Many babies outgrow the seat by height before they reach the 30 lb weight limit.
- Basic Canopy: The sun canopy is a good size but offers basic coverage.
- Harness Adjustment: You have to manually rethread the harness straps as your baby grows, which can be a small hassle.
Recommendation
You should buy the Chicco KeyFit 30 if you want a simple, reliable, and easy-to-install infant car seat. It’s perfect for parents who value a lightweight carrier and a proven track record. If you plan to switch to a larger convertible car seat sooner rather than later, the KeyFit 30 is an excellent and cost-effective choice.

Is Chicco KeyFit 35 Good?
The Chicco KeyFit 35 feels like a modern upgrade to the original. The first thing I noticed was the anti-rebound bar on the base. This is a great safety feature. The seat itself feels a bit heavier, but the build quality is excellent. The ClearTex fabric has no added chemicals, which is a nice touch for sensitive baby skin.
The installation is just as easy as the KeyFit 30. It uses the same bubble levels, leveling foot, and SuperCinch LATCH tightener. The big difference is the added features for growth and safety. The Easy-Extend Headrest System is a game-changer. You can raise the headrest and harness together with one hand. No more rethreading straps.
What I Like
- Longer Use: It fits babies up to 35 lbs and 32 inches tall, so you can use it for more months.
- Anti-Rebound Bar: This bar on the base increases stability in a crash and provides extra legroom for your growing baby.
- Easy-Extend Headrest: The 5-position headrest and no-rethread harness make adjustments incredibly simple as your child grows.
- No Added Chemicals: The ClearTex fabric is GREENGUARD Gold certified, meaning healthier air quality around your baby.
- Better Canopy: The canopy offers full coverage and has a zip-open mesh panel for airflow.
What Could Be Better
- Heavier Carrier: The seat and base together weigh 18.5 pounds. The carrier is heavier than the KeyFit 30, which you will feel when carrying it.
- Takes Up More Space: The anti-rebound bar means the seat needs a little more room in the back seat. This could be an issue in smaller cars.
- Specific Newborn Insert: The newborn positioner is designed for babies from 4 to 11 lbs, a smaller range than the KeyFit 30’s insert.
Recommendation
The Chicco KeyFit 35 is for parents who want the latest safety features and want to keep their baby in an infant carrier for as long as possible. The anti-rebound bar, extended legroom, and no-rethread harness are significant upgrades. If you don’t mind a heavier seat and have enough space in your car, the KeyFit 35 is a fantastic long-term choice.
