    • Perfect
Color: Fathom Style: MyFit
The Chicco car seat is easy to install, very sturdy, and feels safe. My child is comfortable in it, and the straps adjust easily. The cover comes off for cleaning, which is super convenient. Excellent quality and worth every penny!

    • Great seat for special needs kiddos!
Color: Nightfall Style: MyFit with Zip and Wash Fabric
Update: 07/31/25 Update My grandson (now 8.5y) has been in this car seat for a little over a year; it’t been in booster (seatbelt) mode for about 6 months. He is now 48 inches tall, and weighs 45 lbs. For those of you with special needs kiddos, know that he would still fit comfortably in the harness of this seat, if needed, with another notch in the headrest available, if we needed additional time in the harness. I still really, really like this seat, but there is one thing I don’t like. The zippers on the seat pad of this seat split constantly. And I don’t mean they come unzipped; I mean they actually split in the middle from him getting in and out of the seat, and kicking his legs back and forth while in it. Had I known this, I would have saved some money and bought the cheaper one. Still, he has at least another year in this seat in booster mode, so I am still a fan of this seat. Highly recommend! ******************************************************************************************************************** 5/10/2024 (original post): First, let me say that this seat is for older, bigger children. It cannot rear-face, and while the minimum weight is listed at 25lb, for safety reasons, children of that weight should remain in a rear-facing seat until they outgrow it. I ordered this seat for a few reasons. One reason was that I needed a seat with a higher harness limit than most standard seats. The harness on the My Fit goes to 19.5 inches from the seat; 1.5 inches higher than our Graco 4Ever DLX. My grandson is 7.5yo and is ASD level 2; he is wiggly and impulsive, and definitely not ready for booster training yet (we’ve tried). For reference, he is 46 inches tall and weighs 42lb. According to my research, each inch of seat height is roughly equal to one year of growth. He has a couple of inches of growth room in the My Fit harness, and hopefully will be more ready for a booster in the next year or so. I have done much reading over the past month, and I am impressed with the safety ratings of this seat. I also like the thick, comfortable padding. My son and DIL have had the base model of the My Fit in their car for the past two years (the cover does not zip off), and they really like their seat. I chose the My Fit Zip model with the zip-off lining, and I would urge anybody who has a child not fully potty trained, or one that drinks in the car seat, to upgrade to the My Fit Zip. It is worth the extra money to be able to unzip the pads and toss them in the wash without taking the whole seat out of the car to remove the cover. I installed the seat using the vehicle seat belt, because my grandson weighs more than 40lb. I have a 2022 Mitsubishi Eclipse Cross. This seat is a bit bulkier than our Graco 4Ever DLX, and weighs a couple of pounds more, but it fit well in my vehicle and it was as easy to install with the seat belt as our Graco was. The width of the seat is listed as 17 or 17.5 inches on several review sites, but the width of the seat where it meets the vehicle seat back is roughly 11.5-12 inches, so it will fit in smaller cars. I am extremely happy with the quality and heavy-duty construction of this seat; it is well worth the money we paid! ... show more

    • Beyond happy with this purchase
Color: Shadow Style: MyFit with ClearTex No Chemicals
Chicco has been my go-to for car seats. I couldn’t be happier with this purchase. So much so that I even convinced my sister she needed the same seat. This is easier than most to install because it gets tight without having to use every ounce of your strength. I thought black would absorb heat but it really doesn’t so it stays cool when it’s in the hot car. We’ve traveled with it and it’s not this massive, overweight thing to carry. It’s lightweight (compared to most other brands). It feels safe too. Sturdy and you can just tell it has great quality. It was also super easy to switch from harness to high back booster. I love that it has compartments to store the harness straps away so we don’t have to completely dismantle the thing to get the harness off. The cup holders folding in has been way more helpful than I thought too. Didn’t understand why we needed that feature until I tried to install another car seat next to this. Okay, got it now! I will never go back. It will be chicco for me from here on out. ... show more

    • Sturdy, safe, comfortable, versatile
Color: Shadow Style: MyFit with ClearTex No Chemicals
I LOVE this harness booster seat. No crazy chemical smells out of the box, its pretty easy to put in besides its weight. It is very heavy but it makes it seem sturdy which I like. So far it seems well made and I really enjoy that it can sit up and recline. My little one loves it too. I went with this model because my 4 yr old is technically big enough for a booster but shes so young still I wasn't ready to put her in one. The 5 point harness option was the deciding factor not to mention we've used chicco carseats her entire life. They were also the most affordable highest rated crash test from my research. (I can't spend $800 on one car seat but I'll gladly spend $250 on this one.) It's versatile and seems safe. Love this car seat/ booster. Also we've had it for a few months now and it's held up beautifully so far. Haven't washed the cover yet but I did on our old chicco zip n wash. If its anything like that one it will be just fine when it needs cleaning. My daughter loves it too. She says its comfy. ... show more

    • Such a great harness booster!
Color: Nightfall Style: MyFit with Zip and Wash Fabric
Review Image by Jensookim Jensookim
Chicco is the best, installation and adjustment is always super easy and the quality is I quite top notch. We have a Keyfit infant carrier seat, a convertible Nextfit, two Gofit backless boosters and this Myfit. We've had several other brands and also keep going back to Chicco. My 6 year old has been in this seat since he was 4 and aside from a little dirt it looks new. It is comfortable, durable and it looks nice in my car. I don't dread reinstalling any of my Chicco car seats like I did my evenflo or diono seats. ... show more

    • Keeps their heads up when napping!
Color: Fathom Style: MyFit
These car seats are amazing. I have a 3 and a 5 year old. I was looking for something to graduate them from their 5 in 1 car seats they had since babies. This is the perfect kid car seat. Very comfy, easy to strap in and out. The most amazing part is that when they nap in these seats, their heads don’t keep bobbing down, which gives them a much better quality sleep. Not many reviews talk about this, but it is by far the best feature of a car seat. ... show more

    • Comfiest seats around.
Color: Haven Style: MyFit
Went through 2 other boosters for both kiddos. Couldn’t pass these up. These are tall, wide and soft. They attach to the anchors in the can easy. There are a lot adjustments for the seats to make the kiddos comfy. Have both options of harness or seatbelt!
