2 months along I'm pretty happy this was the biggest splurge in our baby purchases, and that we rearranged our budget for it (pricey car seat, secondhand baby clothes) rather than buying a cheaper car seat. Considering how long we'll use it, and that it's so highly rated for safety and ease of use, it made more sense than spending a lot elsewhere.

The pros:
-- Highly Rated by Consumer Reports
-- Very easy, even for this car seat newbie
-- LOVE the newborn insert for babies under 10 lbs, since most aftermarket car seat additions for floppy newborns compromise the safety of the seat.
-- The Adventure fabric is indeed more breathable than some others
-- It rocks smoothly! It's easier to put baby to sleep by rocking his car seat on the floor, than in the swing and so on.
-- Little One seems very comfortable in it. It's a preferred napping spot out of the car (just be very aware of the danger of loose straps if you do this; I keep him buckled, or fold the straps underneath, add a blanket, and then put him in the seat.
-- We've had no problems with his head flopping around (from the size of 8.5 lbs, 21")
-- Pops into the base easily, making it simpler to mount it in the middle rear seat

The cons:
-- He does get a little bit sweaty in the seat (even though we ordered Adventure, which Chicco's customer service had said is a more breathable fabric). We combat this with a burp rag flat behind his back for one thin layer of wicking, and with a cloth (cotton) diaper with a wool cover (no synthetics). I can't imagine how uncomfortable he'd be in disposable diapers in it.
-- The canopy does not pull up or down well
-- It's immensely annoying to have to push buttons on both sides of the handle, to move the handle
-- No slot to set it on a grocery cart. True that's not the safest spot for the car seat but it'd be nice to let parents choose. Sometimes I want to set him there for just a minute, when the cart is not moving and nobody is moving near it (like in the checkout line).
-- The additional safety features do make it heavy
-- The base is frequently out of stock so take care to get the spare well before you need it

Editorial Review

Chicco KeyFit Infant Car Seat and Base It's very rare to find an infant car seat and base which work together so greatly to make the entire installation process easier. The KeyFit Car Seat and Base from Chicco works so well together that it is very different than other car seats. Other car seats don't install half as easily as the Chicco. The KeyFit is a baby car seat which is also affordably priced to not bust wallets. The KeyFit can fit a range of child form 4-30 pounds
