Azar –
Great, a lot better than the old one it replaced
Charles Petrie Jnr –
Good quality price appropriate car seat bought for seven year old granddaughter who seems very happy with it. Is a good size, appears to be comfortable and she likes using the seat belt, being ‘a big girl now’.
David ROSHER –
This is my repeat order for my second child and I am completely satisfied with the quality and value for money
Sean T –
Good booster seat, made of plastic but has some form of foam cushion attached. Made well, lightweight.
Jodie Steele –
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!
Joe –
Very smart and compact, well known easy to function and comfort to use, which also money valued.

Perfect upgrade and keenly priced.
Better quality finish than equivalent own brand stuff at Halfords.
No complaints from it’s occupant.
