  • Car Seat Dimensions and Weight

The car seat measurements differ between the two variants. Britax B safe 35 is 26.5″ by 17.8″ by 25″, while the Chicco Keyfit 30 is 27.5″ by 17″ by 24″. When it comes to weight, Britax is less bulky, weighing only 12 pounds, whereas Chicco Keyfit 30 is somewhat heavier, at 17 pounds. Despite the minor differences in dimensions, we find the two car seats to be compact. When compared to other cars, the weight isn’t as oppressive.

  • Height and Weight Restrictions

The Chicco Keyfit 30 is great for babies weighing between 4 to 30 pounds. It is recommended that the baby’s height not exceed 30 inches. The Britax model seems to have a wider weight range, accommodating newborns weighing between 4 and 35 pounds when rear-facing.

It also outperforms the Chicco brand in terms of kid height, as it can accommodate children who are 32 inches or shorter. In practice, though, the two seats appear to be about the same height from the shell to the top. You may not notice the change.

  • Washing Characteristic

The Chicco Keyfit 30 covers seem to be machine washable and detachable. In the incidence of diaper spills, milk drops, and other mishaps, the material is easily washable. Although you may remove the strap covers and search for detachable ones, we desire the strap covers could be removable for cleaning.

These belts aren’t washable to protect the fire-retardant characteristics, which could be compromised if washed. Britax B safe 35’s are not washable in the washing machine. However, they are hand washable, which can be a pain if you use them frequently.

  • Installations

You can install the Chicco model in three different ways. Chicco Keyfit 30 installation is simple through the use of super Cinch LATCH, travel correct bubble levels, or the recline sure leveling foot. Britax B Safe 35 repair is nearly identical to the Chicco model, although in two aspects. To tighten the baby car seat, utilize seat belt locking offs or a safe center latch.

Assembling the base at the proper level and reclining angle is simple in both models, albeit the LATCH pull-strap system on the Chicco makes it a lot easier than the Britax B Safe 35. Dual-level indicators are built into every car seat to assist you in setting the right reclining angle. If you’re feeling overwhelmed, an easy setup handbook can help you comprehend the setup process and car seat capabilities.

Similarities of the Chicco Keyfit 30 and the Britax B Safe 35

  • A number of Harness points

Each car seat has five harness points to ensure safety and a precise fit. On both variants, the harness end is near the shoulder for a better fit. The fastening belt connects without difficulty. When fastening the youngster in, adjusting the buckles is also simple. When comparing the straps, the Britax B Safe 35‘s are a little thinner, and as a result, they twist more frequently. The buckles on the Chicco Keyfit 30 are a touch thicker, so they don’t twist as readily while you’re removing the infant.

  • Comfort

For comfort and convenience, both car seats have proper pads safety. Each model has a machine-washable soft cloth. Because the material is airy, the baby does not swat during long car rides in hot weather. Even when it brushes against the baby’s skin, it isn’t itchy.

  • Protection From Side Impacts

In the case of a crash, the crumple zone cushioning is soft enough to cushion the baby’s head and body. For impact management, the sidewalls have fine coats of energy absorption material. Because the Britax B Safe 35 only has one layer of protection, we think the Chicco Keyfit 30 offers more sophisticated side impact protection.

  • Compatible With a Stroller

The two-car seats work with specific stroller models. With the help of a stroller adapter, the With the Keyfit 30, you can use the Urban, Chicco Bravo, Neuvo, activ3, Cortina, Cortina Magic, and many other strollers that are not Chiccos. Only Britax B series strollers, as well as all Duallie as well as BOB single strollers, are compatible with the Britax B Safe 35. The click-and-go connector mechanism may not operate with other strollers besides these types.

  • Detachable Canopy

A retractable canopy comes in both car seats. The Britax B Safe 35 canopy is wider and longer than the Chicco Keyfit 30 canopy, and it can shield up to two kids in car seats next to each other while still providing enough shade when completely expanded. Chicco’s Keyfit 30 is too short and may not stay extended all of the time. It isn’t quite as good as the Britax B Safe 35, yet it provides excellent shade for the baby.

  • Color and Price Choices

Both the Chicco Keyfit 30 and the Britax B Safe 35 have a similar price range. Each model comes in various colors to meet the preferences of different users.


Our top pick is the Chicco Keyfit 30. Despite the products having a similar price range, we notice that the Chicco model has additional features not available here on Britax B Safe 35.

Chicco Keyfit has the advantage of superior side shock absorbent and a more straightforward base installation technique. We like that it’s compatible with non-Chicco stroller models and that the straps are thicker and don’t twist like the Britax models. Chicco’s covers may be machine washed. However, Britax cannot.

On the other hand, Britax is the clear choice in terms of its large canopy that remains put and provides a nice environment for vehicle naps.

Regardless, we hope this comparison clears up any confusion about whether the brand is better: Chicco Keyfit 30 vs. Britax B Safe 35. However, both brands are safe and have fantastic recommendations for the baby or newborn.
