Maxi-Cosi Onyx i-Size Car Seat - Full Graphite, Forward-Facing, 15 Months to 12 Years

The Maxi-Cosi Onyx i-Size is a forward-facing car seat designed to provide extended protection for children from approximately 15 months up to 12 years old, or from 76cm to 150cm in height. It meets the latest R129 i-Size safety standards, offering enhanced protection in both frontal and side collisions. The seat is constructed with integrated G-CELL panels, which are engineered to absorb and distribute impact forces, alongside a 5-point safety harness that includes energy-absorbing memory foam in the headrest area for additional security. Key practical features include ten adjustable headrest height positions and a fully adjustable harness system, allowing the seat to adapt as your child grows. It offers five recline positions to ensure comfort during longer journeys, and the harness can be neatly stored when converting the seat for use as a high-back booster. The cover is made from 100% recycled fabric, created from repurposed plastic bottles, and is removable for washing. Installation is via an integrated ISOFIX system combined with a top tether and the vehicle's three-point seat belt for a secure fit. This car seat is best suited for families seeking a long-term, safety-focused solution that transitions from a harnessed seat to a booster. Its design prioritises both protection and comfort, with the adjustable elements helping to maintain a proper fit throughout childhood. The sustainable materials and practical, washable cover make it a durable choice for everyday use, suitable for most vehicles equipped with ISOFIX points.
