Maxi-Cosi Quartz 360 i-Size Car Seat - Full Graphite

The Maxi-Cosi Quartz 360 i-Size is a car seat designed to provide safety, comfort, and convenience for children from birth up to approximately four years old. It is certified to the latest i-Size safety standard (ECE R129) and is suitable for children measuring between 40cm and 105cm in height, with a maximum weight limit of 18kg. The seat can be used in both rear-facing and forward-facing configurations, with the transition point being when the child reaches 76cm in height. Its integrated FlexiSpin base allows for 360-degree rotation, making it significantly easier to place and secure a child in the seat, especially in tight car spaces. Key safety features include G-CELL Side Impact Protection technology, which is engineered to absorb and dissipate energy in the event of a collision. The headrest contains impact-absorbing memory foam for additional protection. For everyday practicality, the seat includes an easy-in harness system with hooks that simplify buckling, and five adjustable recline positions to ensure a child's comfort during journeys. The cover is made from 100% recycled polyester fabric, known as Eco Care, which is soft and gentle on sensitive skin. This fabric is created from the equivalent of over 70 recycled plastic bottles. The Quartz 360 is an ideal choice for parents seeking a long-lasting, feature-rich car seat that grows with their child. Its nine-position adjustable headrest and harness system accommodate a child's growth from infancy through the toddler years. The included newborn inlay provides extra support and a snug fit for very young babies. With its ISOFIX base included for secure and straightforward installation, machine-washable cover for easy cleaning, and a modern design in Full Graphite colour, it combines robust safety credentials with the practicalities needed for daily family life.
