The Chicco MyFit

2-in-1 Comfort & Security

The Chicco MyFit® Zip Harness+Booster is a harness/belt-positioning car seat that is designed to grow with children from toddler through big kid with easy transition from five-point harness to vehicle seat belt. Nine headrest positions accommodate growth throughout both modes and work together with a four-position recline to support proper posture. An extra-deep ErgoBoost® seat with dual-density foam padding is sloped and contoured for superior comfort.

Reassuring Protection

DuoGuard® offers two layers of protection with a rigid shell and EPS energy-absorbing foam that surround the head and torso. The seat shell is also reinforced with a steel frame for superior impact protection.

Zip & Wash Convenience

The MyFit® Zip seat/backrest cushions feature a convenient zip-off top layer that is easily removable for machine washing while still maintaining use of the standard fabrics underneath.

Easiest to Install

The MyFit® is designed with smart functionality that makes it the easiest to install simply, accurately, and securely every time. A four-position ReclineSure leveling system and RideRight bubble levels help achieve and verify proper angle in the vehicle seat. Premium LATCH connectors and a LockSure® belt-tightening system with wide routing make it easy to achieve a tight and secure fit with LATCH or the vehicle seat belt.

User-Friendly Touchpoints

A padded, no-rethread harness with a one-pull tightener provides reassuring security for growing toddlers. The harness easily hides away to create a belt-positioning booster with shoulder and lap belt guides for big kids four years and up. Two dishwasher-safe CupFolders feature easy push-button removal and fold out of the way to save space when empty.

  • Converts from 5-point harness to belt-positioning booster
  • Zip-off backrest/seat cushions for easy cleaning, extended durability and extra padding
  • 4-position, best-in-class recline provides a true range of adjustment
  • DuoGuard® head & torso protection; steel-reinforced frame
  • Deep ErgoBoost® seat with dual-density padding and sloped, contoured design
  • 9-position headrest accommodates growth throughout both modes
  • Premium connectors for installation with vehicle LATCH system in either mode
  • RideRight bubble levels make it easy to verify angle in vehicle seat
  • LockSure® lock-offs and wide belt routing for installation with seat belt
  • 2 dishwasher-safe CupFolders

Usage in Harness Mode

In harness mode, the MyFit® Zip is designed for children who are at least 2 years old, between 25-65 pounds, and up to 54 inches tall.

Usage in Booster Mode

In booster mode, the MyFit® Zip is designed for children who are at least 4 years old, between 40-100 pounds, and between 38-57 inches tall.

Love the Zip

I love the zipping function for this seat. It makes clean up so much easier. We have the version that doesn't zip, too. Zippers help.

Perfect seat for my 4-yo with room to grow!
November 12, 2023
Great seat for my over-90th-percentile 4-year-old! Needed to give our rear-facing seat to our youngest, so we chose this as our son’s “big kid” car seat. He loves the comfort, ease of climbing in and out, two cup holders, and that he can buckle himself. I love that it isn’t overly large, is safe, and he can stay in the 5-point harness longer in this seat than many others I’ve found.
  • Comfort
  • Two cup holders

The best harness booster ever!
March 18, 2023
This is the best harness booster I’ve ever had! I loved it so much I bought another for my son so I could keep both him and my daughter in these until they outgrow them completely. So easy to zip off fabric and wash, and super easy install with either latch or seat belt.
  • Zip off fabric for easy cleaning, compact, easy install with latch and seatbelt, easy to move headrest, comfortable material for child to sit on.
Best Uses
  • Everyday use.

Love this car seat for my toddler! Super easy to install and clean! The zippers are out of the way enough that my daughter isn’t bothered by them at all. I also appreciate that it can support a larger weight limit for the harness mode
  • Easy to install, easy to clean, easy to use
  • Base is bulky and sticks out further than others

I fell in love with this car seat as soon as I opened it, it was super easy to install, looks beautiful, and it’s very comfortable and padded. My toddler needed something less bulky so we went with this one and I’m glad I did.

Sturdy, easy install, comfy, zip seems pointless
April 3, 2022
Car seat is very comfy for my daughter, super easy to install (using seat belt). The zip seems pointless to me. It's just a small section of the cover that zips off and it gets in the way of accessing the crotch buckle and is pretty hard to re-zip. Its much harder to remove than many other car seats I've had. The chest clip cover cannot be removed to clean which could potentially be a problem. The chest clip is also pretty hard to unbuckle. Love this car seat but definitely would not have gotten the zip
  • Easy install
  • Comfortable
  • Fairly narrow
  • Zip is deceiving

The Best for Forward Toddlers!

Great for Tall Kids
February 17, 2022
The zip feature is a nice addition. We’ve already used it twice. The main reason we got this was the talker harness height. Our oldest is 99th percentile and we want her safely harnessed for a couple more years. The only downside is the buckle slips down into the seat crevice often, making it a longer process to buckle in.

All in all we're happy with it. The manual is lacking but that's not on AB that's on Chicco. It shipped quickly, arrived packaged well & didn't take too long to get here. This was my first order with them but won't be my last!
  • Love the higher harness height limit on this seat! It takes up a lot less room than I anticipated which was an added bonus!
Best Uses
  • Perfect for taller kiddos you want to keep harnessed a little longer!
  • Carseat manual leaves a lot to be desired as far as proper use but with a little research & reaching out to CPST we were able to get it installed correctly.

Zip Model not worth the extra cost
March 22, 2021
The MyFit is a great combination seat. Easy to install with the seatbelt lockoff feature and the multiple recline options give it flexibility to fit in a variety of vehicles. We have the regular MyFit and I bought the zip version for our second car-wish I had just stuck with the original. The zip off fabric slides around and the zippers add bulk to the back of the seat. Storing the latch connectors was easier on the original without all the zippers to maneuver around. The cover on the original is really easy to remove and wash, without the extra bulk. My kid prefers the fabric arm rest covers to the fake leather and doesn’t like the zip version as much. Not worth the extra money.

Was looking for a car seat for my extra vehicle and didn’t want to go super expensive. I saw this seat and was impressed with the look of it but read about all the safety features it has. The old saying “you get what you pay for” and how can I skimp on my precious cargos. My grandson loves his big boy seat and says it feels comfortable.
  • Love that I could unzip top cover to wash
  • A bit on the heavy side

Super Comfortable and Easy Install
October 30, 2020
My 3 year old LOVES the comfort of this seat (he has 3 other different seats and always chooses this as his favorite). The install of the seat is super easy after thoroughly reading the manual. The only drawback that I have found, that isn't a big issue for us, is that the seat is very heavy, so it is not ideal if you have to move it in and out of the vehicle often.
  • Easy Install
  • Very Comfortable
  • Easy to Clean
  • LOVE the Multi Recline Options

Great toddler carseat
October 19, 2020
This is a great car seat for a toddler. I have the chicco next fit zip and love it but I needed a second car seat for my husbands car. This one is a little cheaper and when she’s ready it can be a booster. I love that it zips to clean it and the cup holders are amazing on it. I will never buy anything but chicco. Our car was wrecked by our teen son a few months ago and then the car hit by a train and blew up. The chicco car seat frame was still in place. That’s a amazing car seat.

Disappointed I didnt realize this didnt have Cinch fit
June 24, 2020
I like this car seat, but feel like it was slightly difficult to secure on my own. I was thinking this had the cinch latch technology where you pull the #1 strap and then the #2 strap to tighten it securely to the seat. It doesnt. I found it very hard to tighten it up to ensure no more than 1 inch of wiggle room. This will be his last carseat, so to know I will have to deal with this headache for the next 3 or 4 year is pretty annoying.
  • Doesnt come equipped with cinch latch technology

Great car seat!! very nice looking, great materials used. Son loves it. I was not expecting that it would be as nice as it is. Chicco is stepping up !
  • nice materials, easy zip-off cushion on the seat to wash so you dont have to remove the entire car seat just to wash a spill. Roomy, my son seems very comfortable in it (more than his previous Maxi Cosi that was suppose to be for toddlers as well). Love that it reclines , has 2 cup holders.
Best Uses
  • My son is almost 3, so not quite ready for a booster but too big for the convertible Maxi Cosi.
  • none so far.
