Review: Lightweight, Safe, and Super Convenient – Great Booster Seat - The Cozy N Safe Kea i-Size Booster Seat has been a fantastic addition to our car setup. It’s perfect for my 8-year-old, and I love how lightweight and compact it is—super easy to move between cars or take on trips. Despite being backless, it feels very secure and stable thanks to the solid design and i-Size ECE R129 safety certification, which gives real peace of mind. My child says it's comfortable to sit on even during longer journeys, and the sleek Onyx finish blends nicely with our car interior. It's also great that it’s designed for kids aged 6 to 12 (22–36kg), so it should last us a good few more years. Perfect for parents who need a safe, no-fuss booster seat that doesn’t take up much space. Great value and highly recommended!
