Description

The MyFit Harness + Booster Car Seat is designed to grow with little ones with an 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 comfort.

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

The MyFit is designed with smart functionality that makes it easy to install simply and securely. A four-position ReclineSure leveling system and RideRight bubble levels let you know it’s in there correctly. Premium LATCH connectors and a LockSure belt-tightening system with wide routing make it easy to achieve a secure fit with LATCH or the vehicle seat belt.

It’s user-friendly too. 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.

For everyday convenience, the two dishwasher-safe CupFolders have easy push-button removal and fold out of the way to save space when empty.

Love the car seats.
This is a great car seat. The cushioned straps keep them from getting tangled. The kids say they are more comfortable than their other car seats. I love the cup holders as they are more flexible and will hold bigger water bottles. I only wish they were available in a few other colors.

Excellent seat for a toddler. Easy to climb in and out and the toddler feels more independent. Love the mesh backing and sides for hot climate. Easy to install in a sedan, as all Chicco seats. It’s a bit harder to install in a truck.
Great seat

A superb growing age toddler car seat
A very high quality toddler car seat. Well cushioned for comfort and safety. The material is very soft, cooler and easily washable. It is on the bulky side when compared to other brands. I was unimpressed with the traditional clip ons design for the belt straps when compared to the Chicco 360 Revolving car seat we have which has the super easy modern instant snap ons. I would highly recommend this to anyone simply because of the material itself.

I would buy this again.
I love this car seat! I have taken my child and car seat on a cross country road trip. It fits great in the back row of my van. I love the straps; I love that it has 5 levels of reclining; I love how narrow it is; I love the arm rests; I love the safety features.

Great replacement seat
We had to unexpectedly get a new seat for our child due to a car accident. Narrowing down our search to forward facing only that transitions to a booster was overwhelming but it ultimately came down to this seat and another from a different brand. I love how both had steel backs and were highly rated for safety. The colors for the Chicco seat were more appealing and the overall installation was very easy.

Amazing car seat
Very easy installation with clear instructions. Easy to adjust based on size of my child. My child seems to think it’s comfortable and much prefers sitting in this to her last seat. Fabric is durable and easy to clean! We’ll be able to use this for several years and probably through our other children.

Makes travel convenient!
We purchased this for our second born and so glad that we did! No more worrying about bopping their head trying to get them in the car! This makes loading and unloading littles so much easier, and easier on the back, too!
