The i-Size classification (40–150 cm) ensures your child is always secured according to height — not just weight — which aligns with the latest European safety protocols for improved accuracy and protection.

360° Rotational System – Convenience Redefined
The Chelino Atlantis III features an advanced 360-degree rotational mechanism, allowing parents to easily switch between rearward- and forward-facing modes with a simple turn of the seat.
This intelligent design makes placing or removing your child effortless — no more awkward reaching or twisting. The rotation system also enables convenient side access for strapping in your child, saving precious time during busy days.
Whether you’re buckling in your newborn or securing your toddler, this feature ensures every ride begins with comfort and ease.
Four Stages of Comfort and Growth
From the earliest days of infancy to the independence of pre-teens, the Chelino Atlantis III Stages 360 Car Seat evolves gracefully to match your child’s development.
Stage 1 (Infant Mode: 40–105 cm)
Rearward facing for maximum protection.
Includes plush newborn inserts for head, neck, and side support.
Ergonomically reclined to promote healthy spine positioning.
Stage 2 (Toddler Mode: 76–105 cm)
Transition to forward-facing when developmentally appropriate.
Five-point harness provides secure restraint and even weight distribution.
Stage 3 (Preschool Mode: 100–150 cm)
Converts easily into a high-back booster seat using the vehicle’s 3-point belt system.
Reinforced side wings offer continued protection against impact.
Stage 4 (Junior Mode)
Adjustable headrest and backrest adapt as your child grows taller.
Ensures lasting comfort and a perfect fit through every growth spurt.
Advanced ISOFIX with Load Leg Stability
Safety installation is effortless with the ISOFIX + Load Leg system, providing superior stability and minimizing seat movement in the event of an impact.
The load leg acts as an additional anchor point, significantly reducing forward rotation during sudden stops or collisions. This not only enhances protection but also ensures a more secure, rigid connection between the car seat and your vehicle’s frame.
For parents, this means peace of mind and a foolproof installation every time.
Five-Point Safety Harness — Confidence in Every Drive
The Chelino Atlantis III comes equipped with a five-point harness system that secures your child at the shoulders, hips, and between the legs.
This configuration distributes impact forces evenly across the body’s strongest areas, minimizing injury risk in the event of a collision.
The harness adjusts easily as your child grows, ensuring an always-snug fit without compromising comfort.
Adjustable Recline for Ultimate Comfort
Children nap often during car rides — and Chelino knows that comfort matters just as much as safety.
The Atlantis III offers multiple recline positions, providing ergonomic support in both rearward and forward-facing modes. Whether your baby is sleeping or sitting up to explore their surroundings, the seat can be adjusted with minimal effort for optimal positioning.
Extra legroom in rear-facing mode allows older infants to stretch comfortably, extending the usability of this safer seating orientation.
Adjustable Headrest and Shoulder Harness
As your child grows, the Chelino Atlantis III adapts effortlessly. Its adjustable headrest and shoulder harness system allow for easy height customization with a single motion.
This ensures your child’s head and shoulders are always properly aligned for safety, while the deep side wings add an additional layer of protection from side impacts.
Removable Inner Cushions — Comfort and Hygiene Combined
The soft, padded inner cushions offer luxurious comfort and additional support for younger passengers. These inserts can be removed as your child grows, maintaining the perfect fit at every stage.
All fabrics are removable and machine washable, allowing parents to keep the car seat clean and fresh through years of use — an often-overlooked benefit that makes daily life easier.
Built to Last — Premium Materials and Durability
The Chelino Atlantis III is engineered using high-strength materials designed for durability and long-term performance.
From reinforced impact-absorbing shell structures to breathable, soft-touch fabrics, every detail reflects Chelino’s dedication to quality and comfort.
