Love this car seat! Easy install!

We bout the keyfit 30 zip air for our daughter because we live in extreme heat. It kept her from sweating like the original keyfits. It’s easy to take apart due to the zips. Machine washable cover. If you need a new harness you can purchase it easily on Chicco’s site. To adjust the seat harness you do not have to take the seat apart. We used it for two babies and I am super pleased with it!
