⚡ At a Glance
- • Fit & Longevity: Adjustable headrest adapts from roughly 100–150cm, suitable for ages about 3.5 to 12 years
- • Best for: Parents seeking a long-lasting Group 2/3 booster that grows with a child
- • Not ideal for: Families needing a seat for infants or newborns, as this covers Group 2/3 only
High back booster designed for Group 2/3 use from about 100–150cm and roughly 15–36kg. Padded backrest and adjustable headrest aim to keep children comfortable across several years of use.
Secure Side Impact Protection – with G-CELL side impact system
G-CELL is an integrated safety structure that channels and spreads forces from a side impact away from the head, neck and shoulders. The geometry of the cell-like structure reduces force concentration during a collision.
Improved protection around the torso and head helps reduce injury risk in side impacts, making journeys safer for growing children.
Quick, Stable Installation – with ISOFIX connectors
ISOFIX anchors lock the booster into compatible vehicle points for a rigid connection, removing much of the risk of incorrect fitting. Visual or tactile feedback speeds up confirmation that the seat is secured.
Fitting takes less time and is more reliable than seatbelt-only installation, so the seat stays stable on daily school runs and family trips.
Comfort and Ease of Use – thanks to adjustable headrest and simple buckle-up
A height-adjustable headrest lets the seating position change as the child grows, while the design removes bulky armrests so the harness buckle sits unobstructed. Padding in the backrest and seat adds cushioning for longer journeys.
Children can buckle themselves more easily and travel in a supportive seat that adapts as they grow, improving independence and comfort.
