Used it for nearly six months. Baby is very comfortable in it.
Solid construction. Fittings, snaps, handles all secure and reliable and not worn at all after daily use. Easy to adjust the straps.
My advice- most of the seats look similar. They are all plush and colorful. But compare the BASES. The best seat is of no value if the base it attaches to is light and flimsy and likely to fail in the stress of an accident. Go into any store and look at the various replacement bases for the different brands of carseats for sale. You will see right away that the Chicco base is FAR stronger and more substantial and well-built. It gives me confidence that the seat will not pull away from the car attachment in an accident (God forbid)
I would recommend the Chicco KeyFit to a family member or friend without hesitation.

After a LOT of research I decided on the KeyFit 22 for my second child. The Britax B-safe was the runner up but is heavier and a little pricier. For our first child we had had the Graco Snugride but that was purchased in 2005 and had long since been passed on. The KeyFit is a sturdy, well made seat and gets my vote for ease of use and a great price tag! It is very easy to install properly with the easy-to-see leveling bubble and the built in adjustor with a lot of different height options to level it off. I remember taking my first car seat to the fire station to check that it was installed properly only to have them stuff a swimming pool 'noodle' (cut in 2ft lengths) under the seat to get it level. This is soooo much easier!

Quick Pros:
1. very easy to install at the proper angle
2. can be used with or without the base
3. machine washable cover. I have taken it off just to see how easy it was, it only took a few minutes, but haven't actually washed it yet so... Read more

We ordered the Keyfit 22 car seat instead of the Keyfit 30 because it was the lightest option available by several pounds, and we hoped that would make it easier for us to carry. Our baby was 6 lbs. 3 oz. on arrival and carrying her in this car seat has been a breeze. The Keyfit 30 can only be used up to 30 inches in height anyways, and I expect our child will exceed that measurement prior to exceeding the 22 lbs.

I really liked the base installation process with the LATCH system. It was slick. Just attach the two seat belt buckle-like clips to the car's two connectors under the seat. Then pull on the strap while kneeling on the base to make sure it is tight. Finally use the built-in levels to make sure it is right. After about 10 minutes of yanking and wiggling, I definitely felt that it was installed correctly.

We ordered a second base so that we have one in both of our cars and that has already come in handy. Well worth the investment to have the flexibility... Read more
