The NextFit? iX fits your vehicle and your child with proven SuperCinch? LATCH functionality and a new LockSure? vehicle belt-tightening system, plus easy-to-use adjustability designed to comfortably accommodate growing children up to 65 lbs.

NextFit? iX Zip Air+ features a 9-position ReclineSure? leveling system and dual RideRight? bubble level-indicators to help achieve and verify proper angle in the vehicle seat. For installation with LATCH, premium connectors and a SuperCinch? tightener help achieve a secure fit with a fraction of the effort. (When it?s time to switch from rear-facing to forward-facing, the LATCH strap passes easily through the built-in slide path for proper repositioning.) For installation with the vehicle seat belt, a LockSure? belt-tightening system makes it easy to position, tighten and lock the belt into place.

NextFit? iX Zip Air+ is engineered to last with built-in ?fit-ability? for every stage, including a full-body newborn positioner and smooth one-hand headrest adjustment with nine positions. As the headrest is raised, the shoulder strap position also raises and widens to accommodate growing children without re-threading. The harness also features an easy-pull, force-multiplying tightener and machine-washable shoulder pads. For easier in/out, NextFit? iX Zip Air+ is equipped with a padded ComfortFlex? harness management system that holds both sides of the waist belt out of the way until the child is ready to be buckled.

NextFit? iX Zip Air+ has a steel-reinforced frame and is lined with EPS energy-absorbing foam for superior side-impact protection.

I loved this seat. It fit my oldest son perfectly and I had intended on passing it down to my youngest son after he outgrew his infant seat. We unfortunately had to throw this seat away and when I came to repurchase it I saw it was discontinued. I’m so bummed!
  • Easy to install, easy to clean, comfortable, breathable.
  • Cup holder was hard to get drinks into, bulky.

Large and safe
November 29, 2020
My son has used this seat for about a year and a half. It’s very easy to install rear facing but it is huge and weighs a ton! Not recommended if you’ll be traveling or moving between cars frequently! It has gotten good safety scores, which was my primary concern, but my son also finds it comfortable. Lacks clips to keep harness open (minor annoyance) and side wall is very high, so if you have a small car, may be hard to get toddler in and out.
  • Safe, easy to install
Best Uses
  • Primary Convertible car seat
  • Very heavy! No clips for keeping harness out of the way (which is should have given price-point)

awesome seat
October 23, 2019
We were trying to decide between this and the Graco 4ever, and ultimately decided on this, reasoning that we could always get a separate booster seat later, instead of being stuck with a seat we potentially didn't like. So far, this seat has been great. Easy to install, and seems very comfy for my daughter. We're actually buying a second one for the other car.

Great Seat!
September 24, 2019
Shipped perfectly, the seat was mostly easy to install, did have a small issue with the lap belt portion of the seat belt not wanting to tighten completely, but it did eventually. The seat has a good fit, my daughter seems MUCH more comfortable in this than in her infant seat, the shoulder pads are nice and cushiony but don't interfere with tightening. The tightening strap is so easy to tighten or loosen. The sides of the seat are a bit high, and the seat is in our large truck so it does make getting her in and strapped a little trickier, but I feel like it's safe so that's the most important part. It also does seem to keep her quite a bit cooler than her last seat.

Did a lot of researches about convertible car seat, and this impresses me. I love it so much, the color is a beautiful, very easy installation, it only takes 3 minutes to put into my car, and adjustable angles for my baby to have a different view, the cool pad does work, very easy to put my baby in and out, easy to use the stripe. so far, strongly recommend!

Easiest LATCH Install
July 27, 2019
I love how easy the special LATCH multiplier system makes installing this seat. I have been test driving cars and installing it has been a breeze in various vehicles. The zip is a great feature for easy cleaning. My son has been comfortable in this seat and I feel great knowing how safe he is. This was a great purchase.

The extra $ for zip convenience is well worth it!
July 26, 2019
Being able to unzip the top of the seat and throw it in the wash makes a huge difference! And the kids do seem to stay cooler in these seats, but the weather has cooled here since buying them also so it's hard to tell if the seat actually allows more air in or not. We haven't tried the insulated cup holder yet, but I am a little worried about all the other stuff my 3 year old puts in there making it messy and hard to clean out. Chicco brands are much easier to install at a good angle than the gracco ones we have and they come out in a cinch where the gracco ones have taken my husband and I 30 minutes to get out before! Overall we really like this seat and are very happy with our purchase.
  • Easy install
  • Easy uninstall
  • Easy clean up with zip
  • Feels like a good sturdy seat
Best Uses
  • Rear facing
  • Forward facing
  • Cup holder may be hard to clean messes out of

Chicco will always be Chicco... Amazing!
July 22, 2019
We have a consumers report account and Chicco is rated #1 for years. Now that we have two kids we keep trying to considered other brands when it came time to upgrade the infant seat to a convertible. We’ve researching for over 6 months for the most comfortable, high quality and most security seat. Chiccos are very bulky and big, but extremely easy to install. My older son has the big kid seat and my baby the convertible one.
We love Chicco. We have bought seats next to each other in a regular Prius.

Just what I expected
May 31, 2019
Initially found and researched this seat on It is heavy but that lends to its safety and features; I didn’t expect to be moving this seat from car-to-car each day like I did with our infant seat.
Definitely recommend this seat if the cost of owning two is not an issue.
  • Pros: insulated cup holder (yes, my daughter uses this), suitable for infants (included padding) but grows with the child (faces rear and front) and easy on-the-fly height adjustment, very easy to anchor and secure in a car, upright/recline adjustable, padded straps, and one-zip removable cover for washing.
  • Excellent CR rating.
Best Uses
  • Due to weight and lack of a handle, we opted to purchase one for each vehicle.
  • Cons: upright/recline adjustment requires loosening anchor straps when rear-facing and no handle or hold for carrying when outside vehicle.

Comfy but bulky
May 3, 2019
My LO outgrew her Chicco keyfit 30. We did a lot of research online, and we narrow down our choices to Chicco Nextfit, Maxi Cosi Pria 85, and Britax BLD or Advocate. We have good experience with Chicco keyfit, so we decided to go with Nextfit. Our LO sweats a lot, so we got the Air version for her.
She seems to be very happy with the new chair.
  • Breathable, easy to install
  • The only pro we don't like is it is very bulky, especially for rear-facing at this stage. We have a ford explorer. After putting the car seat in the middle of the 2nd row, we cannot get access to the 3rd row since the neither side of the 60/40 can be folded. Since our dog always gets into the trunk from the back, it is not a big issue for us now. But I really don't see a way we can fit Nextfit into our CRV without compromising the recline.

Great seat, seems comfy. I had no issues installing it in the middle seat of my X3. Though it definitely wouldn't fit another carseat right next to it.

March 22, 2019
The buckle is a little difficult to push. The design of the pull and release for the straps seems to be located in an inconvenient location when the seat is rear facing. Other than that the seat fits great and appears very well made.

Great Upgrade
March 8, 2019
We just recently upgraded to this seat from the Chicco KeyFit 30. Our daughter loves her new seat. I really think she enjoys sitting up higher. Thus far I believe the air feature has helped her stay cool but we havent reached summer yet. Love that this seat can be used rear facing for so long to have added comfort and protection!

Bought for my 9 month old as she is getting too long for her infant car seat. Glad I spent the little extra for zip and air. Enjoying the extra features they have. Belt lock offs were a must for me to make sure the car seat is installed safely. No complaints, very happy with the purchase, we will be buying a second for our other car.
  • Ventilation
  • Comfort for baby
  • Seat belt lock off
  • Quick and easy latch system
  • Well made with safety in mind
  • Minor con- Cushion around buckle does not stay put well. I could just remove it but I like the added comfort for baby.

November 19, 2018
What base do I buy for this car seat? Or is it included?
This is a convertible car seat. This type of seat does not have a detachable base. The entire seat needs to be moved and installed.
