About this item

Product details

2-in-1 Comfort and Security

The Chicco MyFit® Harness + Booster Car Seat is thoughtfully designed to grow with your child, transitioning seamlessly from a forward-facing five-point harness to a booster mode. With nine adjustable headrest positions and a four-position recline, it ensures proper posture and comfort throughout every stage. The extra-deep ErgoBoost® seat, featuring dual-density foam padding, provides ergonomic support for superior comfort.

Space-Saving Design

Perfect for families on the go, the MyFit® boasts a slim design that fits three-across in the backseat without compromising comfort for children or passengers. The innovative CupFolders™ conveniently fold in when not in use, maximizing space and maintaining a clutter-free interior.

Enhanced Safety Features

Safety is a priority with the MyFit®, which includes EPS energy-absorbing foam surrounding the head and torso, along with a steel-reinforced frame for superior impact protection and stability. These features work together to provide peace of mind during every journey.

Effortless Installation

Installing the MyFit® is simple and secure, thanks to its smart functionality. The ReclineSure™ leveling system and RideRight™ bubble levels help achieve the proper angle in the vehicle seat, while premium LATCH connectors and the LockSure® seat belt locking system ensure a secure fit using either LATCH or the vehicle seat belt.

User-Friendly Adjustments

Designed with convenience in mind, the padded, no-rethread harness features a one-pull tightener for secure adjustments as your toddler grows. For older children, the harness can be stored, transforming the seat into a belt-positioning booster with shoulder and lap belt guides for kids aged four years and up.

Our littles are satisfied with our purchase.

We purchased two of these chairs since we have twins, and my twins absolutely love these chairs. We wish the cupholders were designed a little different since not all their cups fit in them or the ones that they prefer installing was fairly easy. You definitely have to put in some elbow grease in order to tighten so that it does not move and we also had to strap it down from the back. The price is a little high. We wish we would've gotten a little bit better of a deal since we bought two at the same time but overall, we are pretty satisfied with our purchase.

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.

MUST BUY

Originally ordered this car seat because my daughter naps ALOT in the car and her head would always fall forward and made her uncomfortable but this car seat has been an absolute game changer in our car rides. It reclines back far enough her head does not fall anymore and it stays in place.. 10/10 would recommend for toddlers. It has put my mama heart at ease and I’m beyond thankful for that!
