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

Maxi-Cosi Quartz 360 Car Seat — Comfort, Safety & Convenience from Day One

The Quartz 360 offers everything parents need in one smart package — comfort, safety, and convenience — designed to keep your little one secure from birth up to 4 years old (40–105 cm). Equipped with a cozy Newborn inlay and five recline positions, it ensures your child travels in comfort at every stage.

Safety You Can Trust

Featuring integrated G-CELL side impact panels and a memory foam headrest, Quartz 360 protects your child during side collisions. The secure 5-point harness keeps them safely restrained. The innovative FlexiSpin 360° rotating base lets your child ride rearward-facing up to 4 years for optimal safety, or forward-facing from 15 months when you’re ready.

Designed for Ease

Loading your child is hassle-free — simply rotate the base toward you and slide them in. The easy-in harness hooks keep straps open and out of the way for quick, fuss-free buckling.

Grows with Your Child

From day one, the included Newborn inlay provides essential support, then can be removed as your child grows. Adjustable headrest and harness height positions help maintain the perfect fit as they grow, all the way to 4 years old.

Superior Comfort

With five comfortable recline settings, your child can nap, relax, or sit upright comfortably on every journey. Soft, breathable Eco Care fabrics enhance comfort while keeping skin happy.
