Why Parents Love It
Easier, More Secure Installation
The ClickTight Installation System uses a built-in tensioner and locking mechanism to tighten and secure the vehicle's lap-sash belt. The self-tensioning system helps keep the seat firmly installed until the ClickTight panel is opened, while an integrated coloured belt path provides a clear visual guide during installation.
Harnessed for Longer
Unlike a regular booster that relies on the vehicle seat belt to restrain your child, the B-Grow Lux uses a built-in 6-point harness to support them across the shoulders, hips and torso. Your child can continue using the harnessed seat while they remain within the permitted shoulder height markers.
Advanced Side Impact Protection
Dual-layer SICT provides additional side impact protection at both the torso and headrest. The deployable system uses crumple zone technology designed to reduce energy transferred during a side impact while maintaining interior vehicle space.
A Better Fit as They Grow
The Grow-With-You crotch buckle provides four adjustable positions using a press-slide-lock system inside the ClickTight frame. Combined with the easy-adjust headrest and Hassle Free Harness, it allows the restraint to be adapted as your child's size changes.
Comfort for Growing Kids
A deeper seat provides additional leg support as your child grows, while the generous internal seating area, cushioned inserts and soft trim padding add comfort. Two seating positions and convenient slide-out cup holders make the seat practical for everyday journeys.
Designed for Easier Buckling
Magnetic harness holders keep the straps out of the way while your child gets in and out. The harness adjuster button is also positioned lower and inset into the seat shell to help prevent your child from accessing the harness adjustment system.
A Slimmer Fit Across the Back
At approximately 472 mm wide, the B-Grow's narrow exterior is designed to help accommodate multiple child restraints across the back seat of most vehicles. Actual fit will depend on your vehicle and the other restraints being used.
Knowing When They Have Outgrown It
The B-Grow Lux uses lower and upper shoulder height markers to determine suitability rather than age alone. Once your child exceeds the upper height marker, they have outgrown the seat and will need an appropriate next-stage restraint.
Compatibility
- Forward-facing installation only
- Suitable from approximately 6 months to 8 years, subject to shoulder height markers
- ClickTight system installs using the vehicle's lap-sash seat belt
- Not aircraft compatible
- Vehicle and other child-restraint dimensions should be checked when planning a three-across configuration
