The Maxi Cosi Mico 30 car seat is a top-rated carrier with many positive reviews on consumer reports. Many parents appreciate its safety features, ease of installation, and ergonomic handle. 

Maxi Cosi Mico 30 focuses on the baby’s first year of life. It fits children up to 32 inches in height and 30 pounds in weight. Suppose your newborn weighs four pounds, no need to worry about the fit for a few months. The carrier comes with a comfy infant pillow to support the baby’s neck and head. 

Toting your little one around can quickly become tiring. Maxi Cosi makes this infant car seat with lightweight materials amounting to only 8.1 pounds. It’s easy on the arms, plus the handle is contoured to curve around your hip.

Similarities Between Maxi Cosi and Chicco KeyFit 

Great Alternative

  • Lightweight
  • Self-wicking fabric
  • Easily removable fabrics for cleaning
Best Value

  • Weight Limit 

The Mico 30 and KeyFit 30 have a weight limit of 30 pounds. They can safely accommodate newborns and infants starting from four pounds with the help of the included inserts. The additional support is optional on the two seats, so you don’t have to include it when using either carrier. 

  • Stay-In Car Base

You don’t have to buy a separate car base when purchasing these seats. You’ll get superior-quality bases that work seamlessly with these carriers. You can still buy an extra car base for a second vehicle if you tend to switch. 

  • Can Install without the Base 

Many parents also hail taxis, and these car seats make it easy to use them without the base. Although none have a European-style belt path, they still meet Federal safety standards. The seats will install without the base when you pass the car seat belt through the front of the carrier.

Differences Between Maxi Cosi and Chicco KeyFit 

  • Safety Features 

The Maxi Cosi Mico 30 and the Chicco KeyFit 30 do not have a shock-absorption chamber,  a load leg, or a rebound bar. But, the KeyFit 30 has EPS to absorb impact. EPS is an industry standard for energy protection. 

EPS is now outdated and is being replaced by EPP (Expanded Polypropylene). Mico’s five layers of padding provide similar if not equal impact absorbing capabilities. 

  • Safety Rankings 

According to the many crash tests done on the two car seats, Chicco emerges way ahead of the Maxi Cosi. It scores high in head-impact score (HIC), front-impact crash tests, and sprints way ahead of other models twice its price tag. 

  • Ease of Installation 

The LATCH system on both infant car seats makes it easy to attach them to the car’s base. These are not convertible seats, but Chicco KeyFit has a leveling system while the Maxi Cosi does not. So, KeyFit 30 ensures you will install the seat at the correct angle each time. 

Small piece of fact: the highest causes of safety issues in car seats come from seats installed at the wrong angle. 

  • Comfort for Baby 

Maxi Cosi is winning it here as it includes five extra layers of padding for a snug ride. The adjustable canopy also stretches way ahead of the Chicco. The only qualm we have is that it does not extend to cover the legs, but this drawback is on both models. 

  • Ease of Toting 

Yes, you can take both car seats on your arm. Maxi Cosi offers better tote-ability thanks to the contoured handle, and it’s lightweight at only 8.1 pounds. Compare that to the regular handle on the Chicco KeyFit, and you’ll find you’re constantly adjusting it for better carriage. 

Mico 30 looks fancy and exciting in your arm as opposed to the bare exterior of the Chicco KeyFit. 

  • Value for Money 

Apart from costing almost the same, what the Maxi Cosi lacks in safety ratings makes up for in exceptional comfort and convenience. Chicco KeyFit 30 ticks lots of good boxes, but it ultimately doesn’t match the Maxi Cosi in comfort and toting. 

Conclusion

You could close your eyes and pick the Maxi Cosi Mico 30 or the Chicco KeyFit 30, and we wouldn’t blame you. 

If you live in the city and are worried about getting T-boned, you may have more peace of mind with the Chicco KeyFit. That’s considering its high safety rankings. 

For the parent who wants their baby sleeping in a cozy seat and be able to take your baby with you without crashing into other people on the street, grab the Maxi Cosi Mico 30.
