Harness to Booster

Padded, no-reathread harness accommodates toddlers from 25-65 lbs, then converts to a belt-positioning booster for big kids from 40 to 100 lbs.

9-Position Headrest

Easy-adjust headrest offers extendable comfort throughout both modes.

4-Position Recline

Wide range of adjustment offers improved child comfort and a better vehicle fit.

LockSure Belt System

Easy routing and lock-offs simplify installation with the vehicle seatbelt.

The Chicco MyFit™ harness/belt-positioning car seat 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™ side-impact protection offers two layers of protection for two zones 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.

Easiest to Install

From the makers of the #1-rated KeyFit® and NextFit®, 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.
  • Easy adjust no-rethread harness with 9-position headrest

Great chair, easy to install
June 10, 2021
We've only been using it about a week, but we were pleased to see that we installed it correctly when checking with a carseat tech. One note: you cannot use seat protectors with this car seat - so if that matters to you, skip it.

We bought because our newly 4 year old is giant - 99th percentile in height (45 inches) and he had outgrown the front facing harness height for both his Diono and Clek, even though he was technically within height limits for full standing... his seated height from tush to shoulders was too high. So, check that before you buy any seat!
  • Very tall harness height
  • Easy to install
  • Cup folders are cool
  • Arm rests
  • Can't use a seat protector

I bought this car seat for my husbands car for our 2 1/2-year-old daughter and we loved it so much that we bought one for my mothers car so she can take my daughter with her. It is perfect! It will last us for several years.

This is our 2nd Chicco MyFit we have gotten from albeebaby abd we love them! Super tight install with the lockoff and they are super comfy! My daughter is tall so this is about the only one she can be harnessed in, but I love them anyways!

Best car seat!
May 29, 2021
We’ve owned everything from Graco to diono to Chicco and this is by far the best one. It’s so user friendly and installs like a champ!! It adjusts without having to take it apart and manually move the straps. Huge plus! Soft, has arm rests and is great for drooping/sleeping heads.
  • Soft, comfortable, good for sleeping

Tricky Set Up
April 17, 2021
Getting the seat set up for installation took longer than expected. The directions were super unclear. We had to look online to figure out how to store the latch straps and move the buckle. It took a couple of tries to get the seat tight enough with the seat belt installation in our Mazda3 sedan. We like that it has one of the highest harness height limits so we can keep our tall 5 y.o. harnessed longer.
  • High harness height.
  • Narrow profile.
  • Directions are unclear.

Great for a large toddler
April 9, 2021
I was concerned that it might be too slim for my large 2 year old. Turns out, it's roomy inside the seat. He loves it. We use the recline feature often. It prevents his head from falling forward. It's way easier to loosen and tighten the straps than any other car seat we've had. Very well pleased.
  • Roomy
  • Reclines
  • Easy to loosen/tighten straps
  • Cup holders may be too far away at first.

March 31, 2021
We absolutely love this seat. It came in super fast after ordering and my daughter is obsessed with the arm rests that it has. She never complains about the fit or feel of the seat. Install was a little hard but as we have had to use it more we are getting better at it. The harness is super easy to adjust and the pads on the harness provide extra comfort! The adjustable cup holders are perfect for fitting 3 across in our car. We are super happy with our purchase!
  • Harness is easy to adjust, flexible cup holders, comfort for child
  • Some issues with installing for the first time. Highly recommend reading the manual a few times to help.

This is so nice. It is sleek and works well in my Prius Prime. I am going to buy a second one for my van. My son said it is so comfortable. He is very tall and it accommodates his height with room to grow. It came quickly and the price with a coupon was perfect!

I really love this car seat because the quality is truly amazing. Im a big Chicco brand buyer and this is worth the investment.
  • My kids are on the taller side and most car seats end up being too small quick, not enough space because their growth spurts are out of control! And this gives my 4 yr old a lot of room.
  • The downside but plus side is that it is very heavy at about 24/25 pounds. It makes it more sturdy on the seat but not fun when needing to remove it out the car. Only reason why I gave it 4 stars instead of 5.

August 8, 2020
I have had many carseats and this one is one of my favorites. It is so comfy, has the softest cover and my kid loves it. He's 6.5 and still fits with room to grow so its a long lasting seat. It has a recline and I love that since it is forward facing He is able to still lean back some and not be so upright. Its easy to take the bottom part of the padding off in case of a potty accident too.

Really went back and forth between the chicco myfit and the britax frontier. I chose the chicco because there were too many complaints about the britax harness. Super happy with purchase. My 4 year old is very tall and this seat is perfect for her. Easy to install and isn’t too bulky for my car. Would definitely recommend.

After trying multiple brands of seats, this one is by far the best. The quality it great. The fabric is soft and breathable. It is very easy to get the seat secure and snug unlike many other seats. My very opinionated son has never complained while riding in it. I have been so pleased with the seat that I ended up purchasing another one for my husbands truck.

Easy to Install
May 6, 2020
This is the second MyFit that I have purchased for my child. Love that the material holds up well with frequent washings. It doesn't pill or show wear. It also hides spills and stains well (life with toddlers, am I right?)

My favorite feature of this seat is the anchors and the tether. They come with an easy pull strap that doesn't twist or get caught when trying to tighten!

I would say the only downfall of this seat is that it is heavy. In my opinion this is a seat you want to install and not have to take out frequently. It is a narrow seat, we have this seat and two other car seats in the back seat of a 2013 Chevy Silverado and they all fit comfortably.

We are loyal to the Chicco brand because of the high quality of their products and their no frills design.
  • Ability to disassemble to wash
  • Easy access to anchors and tether

Upgrading my daughter from her Chicco NextFit. I wasn't ready to transition her to a normal booster. I am happy with the harness option and the seat seems very sturdy. Also this company is great! This was the cheapest, with free shipping, and I received it within a couple of days.

We’ve always been a Britax family. However we needed a 2nd car seat and decided to give this a try mainly because of the reviews and the cup holders. Britax doesn’t come with them, you have to purchase separately on convertible car seats. They do offer it on their harness to booster but when I saw that the chicco myfit also offered recline I was sold! My kiddo always falls asleep in the car.I’ve owned Many car seats as I like trying them all and seeing which is best for us (clek,Britax,cosi etc) and BIG on safety and comfort and this is by far my favorite. My kiddos loves his double cup holders for his toys and snacks and cups and they remove easily to clean and I feel safety is definitely met with this seat. Definitely recommend this great car seat.
  • Recline
  • Cup holders
  • Safety
  • Adjustable head rest
  • Good looking
  • Easy to install
  • Crease lines (I hate crease lines) seems like all of chiccos fabric tends to show wear fairly quickly on the fabric.

I got my first myfit harness booster a couple years ago for my older son. My younger son just turned two and I knew he needed one too. These car seats are seriously the best! My kids are so comfortable in them, they have double cup holders, they’re easy to get in and out of! We actually own 3 of the same seat we love them so much. I’d highly recommend this seat if you’re considering it! .

Our favorite booster seat!
February 12, 2020
This is our second Chicco MyFit Harness Booster. It is replacing a different brand (Britax), which we never liked. We bought the Chicco to replace the Britax booster in our main vehicle. The straps tighten and loosen so easily which is convenient, as I'm usually in a hurry when I'm putting kids in and out of the vehicle. We have had a lot of Chicco car seats over the years and they hold up well and have great padding for the kids as well! The cup holders are great too as cups don't tend to get stuck in them like they did our old car seat. All in all, I highly recommend this car seat! Another bonus -- it's not as wide as many different harness boosters on the market, which we needed for one of our cars.
  • Straps are easy to tighten & loosen
  • Narrow in size
  • Cup holders are a great size
  • Great padding

January 20, 2020
We bought this as a step up from the nextfit. My kiddo loves it and so do we. I do wish the latch system was the same as the nextfit though. It works well but not as easy as the nextfit. Would recommend to anyone looking for a great booster!

We bought this carseat because we had to get a convertible carseat for our daughter. We ended up giving her our son's carseat (The Chicco Nextfit Zip which we also love!) We then decided to just do a harness booster car seat for our three year old. He loves it so much! It's also super easy to install and also easy to get in and out of. We highly recommend this product!

My toddler didn’t want to get out
December 13, 2019
We unpacked this car seat and set it on our living room floor. My 2 1/2 year-old climbed in fastened the top buckle and did not want to get out. She was so comfortable! I love that the cupholders are removable for easy cleaning. Our toddler is tall, and I feel like this will fit her for a long time with how high it extends. Our only negative would be how heavy it is. We don’t plan on transferring it from car to car, but if we ever do, it will be a pain with its weight.
  • Removable cup holders.
  • Extends to accommodate tall children.
  • Easy to install
  • Comfortable
  • Ability to recline

Another awesome Chicco
December 13, 2019
We have bought Chicco car seats since Day 1 of becoming a family. We love their carseats and never disappoint. The ease of installation and the comfort for the kid sitting in the carseat is suburb.
We actually had purchased an Evenflo booster seat for our 6 year old. The price was Super cheap, and I figured, it's just a booster seat. But the seat was so uncomfortable that she hated to drive anywhere. The seat belt on the Evenflo would always get tangled. Enough is enough. I bought this Chicco! I wish I had purchased it originally. Chicco is perfection!

Car seat for toddler
November 30, 2019
The Chicco brand is incredibly reliable. I have purchased 7 car seats in the last 11 years. 3 for myself and 4 as gifts. They are built to last and grow with your child. This booster seat is up to 100lbs, has height adjustments and has 3 different recline positions. The padding is thick and makes long car rides comfortable. Easy to buckle and adjust straps. High functionality for moms and dads on the go. Car seat weighs 25lbs, so it’s on the heavier side but it’s durable.

Not all car seats are good options
September 1, 2019
I didn’t realize I needed more compact options for multiple car seats in a minisize SUV. However, most compact car seats don’t last as long as this one and I would have to buy multiple car seats. When you have multiple kids, it’s not really cost effective to keep buying additional seats every few years if you want to keep your kiddos safe for a long as possible.
  • Not as wide as others, but lasts longer than most. It doesn?t make weird plastic noise like other seats we have tried and it installs much better on leather seats than other car seats we have attempted.
  • The bum part is quite tall compared to other seats, so my oldest will hit the ceiling of the vehicle in the third row before she maxes out the height/weight of the seat. It also takes away my visibility faster out of the rear window.

I purchased this for my Son, and it’ll be the last car seat that I’ll have to buy! I love everything about this seat, the design, safety features how easy it was to install in my 08 Dodge Avenger! Also I love that it’s surrounded by a STEAL frame, you can tell it when you pick it up and lift it into your vehicle. My Son loves how comfy his seat is the cup holders are awesome as well. Took me over a year and a half of research and reading reviews on this seat and then talking with friends and I am glad and thrilled to be apart of the Chicco family!

July 3, 2019
So pleased with this seat. Very comfortable, fits my 3 yr old son (36 pounds) perfectly. Keeps his head from falling forward when he falls asleep which I LOVE!!! Install was challenging for me at first. I struggled to get a good secure tight fit. But with practice and really putting tension on the seatbelt as I fed it through the slots to the lock off, it’s good to go now. Tight. Secure. Comfortable. Stylish. A great buy!! Thanks Albee baby for the 20% off and fast shipping. I Highly recommend!

Not worth it
May 9, 2019
Apparently since this car seat does not have the super cinch latch system, it is very difficult to tighten with the latch. Very disappointed in this car seat. Wish I would have known, I would have spent a little extra money on the myfit that has the super cinch latch system. A Chicco advocate called me and explained that in order to actually tighten it with the latch system you have to pull the seat up and align the latch belts evenly for a tight fit. It’s ridiculous!
  • Seat does not tighten by pulling latch belts
