MyFit Harness + High Back Booster Car Seat - 2-in-1 Safety

In this review the MyFit Harness + Booster Car Seat is presented as a practical 2-in-1 option for parents who need a forward-facing harness for toddlers and a high back belt-positioning booster for older children. The single biggest reason to consider this seat is its combination of adjustable comfort and safety: a 9-position headrest, 4-position recline and Advanced Side Impact Protection make it a long-lasting solution for families who want one seat that adapts as a child grows.

Key Features

• Built to Grow: Converts from a forward-facing 5-point harness to a belt-positioning booster so the seat serves toddlers and bigger kids without a full replacement.
• Advanced Side Impact Protection: Engineered to meet FMVSS 213a side impact requirements to provide added protection at the shoulder and head during a crash.
• Easy to Install: Premium LATCH connectors and the LockSure belt-tightening system simplify secure installation in either harness or seat belt mode.
• Ride-Comfort Systems: RideRight bubble levels and the ReclineSure leveling system help ensure a correct angle and a more comfortable ride in many vehicles.
• Comfort Features: The deep contoured ErgoBoost seat with dual-density foam and an adjustable headrest and recline improves long-trip comfort.
• Space-Saving Design: Slim profile fits three-across in many backseats and includes two dishwasher-safe CupFolders that fold away when not in use.

Who It's For

The MyFit is best for families who want a single car seat that covers the toddler harness years and then converts to a high back booster for older children, making it ideal for households aiming to minimize swaps as kids grow. It is also well suited to caregivers who value an easier installation process and a seat that fits three-across in tighter backseat spaces.

Parents who need a rear-facing infant option or a convertible seat for newborns should look elsewhere, since this model is a forward-facing harness that transitions to a booster rather than serving as a rear-facing infant carrier.

Pros & Cons
