ISOFIX for Greater Stability

The integrated ISOFIX connectors allow the Grower Fix to attach securely to the vehicle’s ISOFIX anchorage points. This helps keep the booster stable and correctly positioned on the vehicle seat.

The child is then secured using the car’s standard 3-point seat belt.

Designed for Correct Seat Belt Positioning

The Grower Fix raises the child's seating position so that the vehicle seat belt can be positioned more appropriately across the body.

Wide belt guides on both sides make it easier to route the seat belt correctly and securely.

Comfortable for Everyday Journeys

The anatomically shaped seat and soft padded cover provide a comfortable seating position, while the integrated armrests give the child additional support.

An integrated cup holder keeps a drink conveniently within reach, making the booster particularly practical for longer journeys.

Easy to Use & Maintain

Its lightweight and compact construction makes the Grower Fix easy to move between vehicles when required. The durable fabric cover can also be removed for easier cleaning.
