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

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.
ProsRecline Cup holders Safety Adjustable head rest Good looking Easy to install
ConsCrease lines (I hate crease lines) seems like all of chiccos fabric tends to show wear fairly quickly on the fabric.

Favorite toddler car seat!
March 10, 2020
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.
ProsStraps 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!

Excellent Car Seat!
January 14, 2020
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.
ProsRemovable cup holders. Extends to accommodate tall children. Easy to install Comfortable Ability to recline
ConsVery heavy

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.

My son seems to enjoy his seat. It feels sturdy and safe and is easy to tighten the straps. He really likes putting toys in the little console it comes with but as other reviews said it comes out very easy and frustrates him.

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.
ProsNot 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.
ConsThe 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.

Phenomenal Car seat / Booster Seat!
July 6, 2019
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!

Comfortable Seat
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!

We purchased the Chicco Myfit for my 3.5 year old. The install was hard to get in my honda pilot. Was a better fit in my husbands CRV. My daughter liked the armrests, and she thought it was comfy. I think overall this is a nice seat if you're able to get a good fit. We ultimately replaced them with another brand for the ease of install since we move carseats between cars often.

Confidence in safety and quality
February 15, 2019
Was looking for another car seat my granddaughter could grow into. The Chicco name is very familiar to our family, so there was no other choice as far as reputation and previous experience with safety and comfort. The MyFit harness and booster seat filled the bill for my granddaughter. She seems comfortable now in it, and it will be perfect for the next transition. Durable and easy to clean. The cup holders are an added bonus!

Great carseat thus far
February 1, 2019
This is my first Chicco carseat and it has been installed in our car for two weeks, so this doesn't speak to durability or wear and tear, but so far, I absolutely love this carseat. Installation was a breeze. If you've ever installed a carseat before it is super easy and getting it tight was so, SO much easier than other brands I have installed. My daughter loves it. It took her a bit of getting used to, as the pads under the clips come up to her chin/neck and bug her at times, but she seems to be getting used to it. I have already bought another one of this exact same seat for our 2nd car, that's how much I love it!

Easy Install, My Daughter Loves It.
December 7, 2018
I just bought this seat to replace our Britax Marathon's. We regularly take other kids with us so we bought 4. We keep two in each vehicle. We have a 2011 Ford F250 and a 2013 Toyota Sienna. Our daughter is 5 and 40+ lbs so we use the seat belt to secure the car seat and have never used the LATCH system so I cannot review the functionality of that part of the seat. Now you have some background info, unboxing is uneventful and the seat is assembled and ready to install. It has a nice place to store the LATCH belts when not in use so i tucked those away. The recline feature has 4 settings and we use setting 4 in my truck and setting 3 in the van. It is easy enough to get the seats tight in either vehicle, the lock off system is better than a GRACO Nautilis 65 we own as well. The other seat we loved but is no longer available is a recaro "sport some thing" but it does not offer cup holders. Anyways, my daughter loves it and enjoys riding in it. We have another 5 year old that is with us probably half the week and she lives with her grand parents that allow her to sit in a backless booster and just a belt routing booster even though she is 43" and just above 40lbs, ugh. But she likes these seats better than the backless booster and belt routing booster.

Great HighBack Booster
December 3, 2018
Our truck was in an accident and we had to replace my son's carseat. We decided to get a high back booster and this one fit the bill. He absolutely loves it and he is definitely more comfortable riding in it than his old convertible car seat. I love that even thou is a booster, he is still safe with the five point harness. We have found it to be easy to install in almost any vehicle. s

I got this seat because my toddler was ready for the next seat up and I wanted something that could convert into a booster without a 5 point harness. I have to say I am so so happy with this seat. We are a chicco loving family. After our infant keyfit 30 I got the maxi cosi 70 and did love it at first but then the tighten strap started to shred and we got it recplace and it still over time did the same thing. I love how easy chicco products are to install but the tighten and loosening of the harness is so smooth and effortless. I’ll never stray from Chicco again!

Perfect seat!!
August 22, 2018
After a few month of debate I finally decided on Chicco when it was getting time to turn my son around to face forward. I needed several things from a seat and this met and exceeded them all! He had a Nuna Rava convertible since birth and the reason I didn't keep it was because we bought a new car with a bench in the second row. I wanted all 3 to sit in the second row instead of shuffling one to the 3rd row for easy on and off for school and since my son would be in the middle his Nuna was 1) too wide and 2) really high up making it difficult for me to get him in and out. The width of the chicco is AWESOME! So slim, yet provides lots of growing room. The low profile allows easy entry and removal for me to get him in and out. And the padding is AMAZING. I'm always sooo disappointed in the lack of padding in kids seats. This absolutely delivers in every aspect! The head adjustment is a breeze and I can adjust it without removing the seat. The recline is awesome especially having a car sleeper. I love the padding around the chest clip area he's so snug and secure. And the strap adjustment is amazing too. It's so smooth and easy which makes getting in and out so much faster and easier. Actually I was so impressed sndcin love With the seat I considered buying one for my daughter who is in a booster. So for fun I tried to turn it into a booster just to see and again was betond impressed how unbelievably easy it was for me to turn it into a booster without having to take it in a million pieces, remove straps etc. the design they have is genius! This is a complete win!!!

Fantastic Harness Booster Seat
August 19, 2018
This was a great purchase. The seat was super easy to install. I love the 4 point recline options and the level bubble that shows if the seat is being used properly. I’m a single mom and it took me all of 5 min to install. My daughter is 5, and I want to keep her as safe as possible while riding in the car. She loves the two cup holders, and so do I. They’re easily to remove and toss in dishwasher. The style of the seat is sleek. It’s eash to uncover and wash in washing machine. My daughter says how comfortable it is and that it doesn’t hurt her bottom. The design was done very well with comfortabiility in mind. My daughter can fall asleep and not be slumped over in an uncomfortable position and her neck isn’t all cockeyed either. Before this seat, my daughter was in a Recaro Pro convertible. I switched over to the Chicco because my daughter was too tall for the Recaro and the straps weren’t long enough- her she wasn’t ready for just the seat belt just yet. I am extremely pleased with my purchase and I definitely recommend to any parent who wants to keep their child in a five point harness for as long as possible while riding in the car. We also tested it out to see how easy it was to put away harness and use with a seatbelt- super easy and not complicated.

The MyFit Harness + Booster Car Seat is a great product!T The Car seat is not heavy which is important for installing. The fabric is durable, smooth and easy to clean which is important with children who often have accidents and spills. Installation was seamless, the bubble leveling system makes it easy to adjust matching the seat position in your car! The straps are easy to latch after placing your child in the seat and easy to loosen when removing your child!

I have to say that almost almost all of my products are Chicco and I love them, the quality of these products are excellent! The MyFit Harness + Booster seat is a great addition!

Chicco provided this product to me in exchange for my honest review.

We have always been fan of Chicco seats and this does not let us down. The safety is the number one priority!! It's a comfy seat, reclines, no head droop, narrow enough to put a rear facing convertible right beside it. And, my 3yo loves the cup holders!! I was worried about the rubber padding on the straps but she hasn't complained once and we've had the seat for several weeks

Easy, Comfortable, Clean Lines
July 9, 2018
We were in the market for a car seat that would convert to a booster as our current car seat while yielding a high weight limit, did not offer a booster option. We moved our 1 year old to that car seat and wanted to find a dual option for our 4 year old that was not ready to abandon the 5-point harness. She absolutely loves this car seat. I find the straps adjust and tighten very smoothly and it passed the nap test on our second outing. If it is comfortable enough for naps on long car rides, it is a good fit for our family. Very pleased with our purchase and just ordered another for our second car.

Amazing carseat
June 16, 2018
We just transitioned my son from his convertible car seat to the MyFit so his sister could have his. I went back and forth between this and the similar Britax model. I am sooo glad I choose the MyFit. Not only does my 3 year old love it, I do too. I love that it has for recline positions, the padding around the chest clip isn't rubbery, but more padded and it is comfortable for my son. I have been telling the daycare he goes to if people ask for a recommendation, this is the seat to tell them about! Also, installation was so easy. Took me a matter of minutes to install via latch system. Great product!

Such a great Seat
April 12, 2018
I did lots of research and even bought a couple seats that I had to return before I found this one. I am very happy with it. It was simple to install. I love that is can recline slightly.The best parts for me are that it does not push my sons head forward like some of the others did. Also it is very easy to tighten the straps. I do not have to pull super hard to get them tight and secure. My son loves his "big boy" seat. The cup holders are removable in case you need to squeeze someone beside the seat. The crotch strap is easy to change the position. I feel good about traveling with my son in this seat but he doesn't feel like he is in a car seat and has more room.
