Is the Chicco KeyFit 35 Worth It?

Best infant car seat. Correct installation is what makes a seat safe, and no seat here made it easier than the KeyFit 35. It is the infant seat to buy unless you want the lighter Nuna carrier and will pay for it.

Chicco KeyFit 35 Pros & Cons

Pros
  • Base installed level and tight in 2 minutes in every car, with LATCH or belt
  • Anti-rebound bar and European belt routing without the base
  • Fits newborns from 4 lb with the insert
  • Clicks onto most strollers with an adapter
Cons
  • Outgrown by height around a year for tall babies
  • Canopy is small
  • Heavier than the Nuna PIPA carriers
