The Cozy N Safe Excalibur i-Size Car Seat is a premium, long-lasting child car seat designed for children 76–150cm (approximately 15 months to 12 years). Engineered to the highest safety standards, this i-Size car seat combines advanced protection, superior comfort, and modern design, making it an ideal choice for growing families.
Advanced Safety You Can Trust
Safety is at the core of the Excalibur i-Size. It is proudly recognised as the world’s first Swedish-approved (E5) i-Size car seat, offering exceptional peace of mind through rigorous testing and compliance.
The integrated 5-point harness can be used up to 125cm (around 6 years), keeping your child securely restrained during their early years. For enhanced protection, the seat also features Side Impact Protection, helping to reduce force in the event of a collision.
Designed to Grow With Your Child
The Excalibur i-Size is built to adapt as your child grows. Its unique extended harness system supports children up to 125cm, offering a safer and more comfortable fit for longer than standard harnessed car seats.
A 13-position adjustable headrest allows for precise height adjustment, while the included toddler insert provides additional support and cushioning for younger children.
Comfort for Every Journey
To ensure maximum comfort on short trips and long journeys alike, the Excalibur i-Size includes:
5-position recline, approved for all stages
Deep, supportive padding
Breathable materials that improve airflow and temperature regulation
These features work together to keep your child relaxed and comfortable at every age.
Easy & Secure Installation
Installation is simple and secure thanks to ISOFIX and Top Tether compatibility. The included base support wedge helps adapt the seat to most vehicles, ensuring correct positioning and added stability.
Built to Last
Crafted using high-grade injection molding, the Cozy N Safe Excalibur i-Size Car Seat delivers outstanding durability and long-term reliability—making it a smart investment from toddler to pre-teen years.
