Chicco Nextfit IX Zip Air Convertible Car Seat - Surf

This item is discontinued.
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 from 5 to 65 pounds. NextFit iX Zip Air also features a zip-off seat pad for machine washing and a breathable 3D AirMesh backrest.

Easiest to Install Correctly

NextFit iX 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.

From Newborn through Preschool

NextFit iX is engineered to last with built-in ?fit-ability? for every stage, including a removable infant insert 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 removable, machine-washable shoulder pads. For easier in/out, NextFit iX Zip 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 has a steel-reinforced frame and is lined with EPS energy-absorbing foam for superior side-impact protection.

Easy to clean and instal!
May 20, 2020
Love this car seat. Was going to order the exact one for my 9 month old before I realized it was now discontinued (I’ll get a next fit zip air still) the car seat is wonderful and I feel like it keeps my son completely safe! Only problem is it is pretty heavy but that’s not a huge issue since you don’t even have to completely uninstall it to clean the cover!

Good car seat, but glad I got it discounted
August 5, 2019
I did a ton of research before buying a convertible car seat. My son tends to run hot, so I thought this one would be great with the breathable fabric. I also loved the idea of being able to zip off the liner to make washing easier for spills, etc. I have an Audi Q7 that has latches across all 3 seats, so we have this in the middle seat of the 2nd row. In order to get the base and seat to be level (bubble in the correct area), this is a bit more reclined than my son prefers. He's tall/big for his age, and even with the comfort of the mesh seat, he prefers the car seat in my husband's truck better, which is a different brand, that allows for him to sit up straighter. I also don't like the fact that there are no build in cup holders, and it's almost impossible to keep the straps out of the way when getting him into it.

Best Convertible Car Seat

This car seat is very easy to install and super comfy for my toddler. I LOVE the washable cover - now that I know these exist, I won't ever buy another car seat without a washable cover.

Loved Chicco Car seats
March 16, 2019
Loved out Chicco Key Fit and just received the Nextfit and love it also. It was easy to install and feels so safe. My daughter loves to ride in it and seems comfortable. I really appreciate the option to zip out the liner and wash it and I feel like the air option will be a big plus in the heat of Florida.

Using for an infant
October 10, 2018
This carseat is super cushy for the baby. There are lots of different angles of recline (as my baby is still rear-facing). Its a little annoying having to pick the baby up over the seat to put him down in it. I miss how the infant carseat snapped in and out of the base. But I have to say he is safe and secure. I also think that it was worth the extra money to get the Air edition with the breathable mesh in the back. The baby is a little heat ball surrounded by material.
  • easy to level
  • somewhat big

Very Well Made Carseat
October 10, 2018
I bought this car seat for my great grandson, so I don't have first hand knowledge about it. But my daughter says it is very well made and padded and she loves the recline positions. The baby seems to really like it. He is a very active six-month-old and had a tendency to lean forward out of his old one and then fall asleep with his head hanging over the side. She can recline him more in this one so he can't hang out of it.
  • Very sturdy. Very well padded. Reclines for any situation.
  • Somewhat hard to get the car seat belt through even though she has small hands.

My husband and I love this car seat. We’re huge fans of chicco anyways but this seat is awesome! So easy to move, adjust, and install. My baby girl is so comfy and safe in it and it gives us such peace of mind.

Chicco ix zip air
July 25, 2018
This is my favorite convertible car seat. It does sit high but for a petite child it is perfect.
  • It is so comfortable my child poops every time she sits on it. Which goes to show that the zip part is actually a much needed and used part of the seat as well. It does not take long to dry either.
  • The only con is the latch is a two step system. I like the latch system better on the Evenflo convertible car seat.

Great Convertible Carseat
July 19, 2018
I purchased the Chicco Nextfit Zip Air for my ten month old as she will soon outgrow her Chicco Keyfit 30. We will be moving across the country soon to a much warmer location so the breathable fabric will be perfect. She is already enjoying having more room in her seat and being able to sit a little more upright. This carseat is well-padded and solidly built to keep her comfortable and safe for years to come. We are very happy with our purchase!

Zipper is worth it
June 28, 2018
First, I love the Chicco brand. I am always comfortable knowing Chicco has built a superior product with safety and convenience in mind. This car seat meets those standards. Second, the zipper makes washing the liner much easier than with his Chicco infant car seat. Third, this seat appears to be quite comfy for my child. I'm a firm believer in rear-facing as long as possible and this car seat has provided me that opportunity while keeping my child comfy! My complaint is that the push button to release the straps and remove the child is incredibly difficult to press.
  • Comfortable
  • Easy to clean
  • Exceptional quality
  • Difficult button
