10 Best Booster Car Seats 2025 in the UK

The Graco Junior Maxi i-Size R129 Highback Booster is designed for children approximately 3.5 to 12 years old, fitting heights from 100 to 150 cm and weights up to 36 kg. This covers a wide age range, making it a practical choice for families looking for a long-lasting booster seat. Its 10-position adjustable headrest is a standout feature, allowing the seat to grow with your child and helping to keep the seat belt properly positioned for safety.

Installation is straightforward using the vehicle’s seat belt, with open-loop guides that make it easier to secure the belt correctly. The seat includes retractable cupholders, which add convenience for kids on long trips, and the soft cushioned seatpad enhances comfort. Weighing just 3.49 kg, it’s relatively light, which helps if you need to move it between cars. The booster’s materials include polyester and alloy steel for durability, and it has a sleek black design that many will find attractive.

On the downside, since it uses the car's seat belt for installation rather than a dedicated harness system or ISOFIX, it requires careful placement to ensure safety, so parents should follow instructions closely. Also, while the cushion is soft, some users might want more padding for extended journeys. Its forward-facing only orientation means it’s not suitable for younger children who still require rear-facing seats. This booster represents a solid mid-range option for parents seeking a safe, adjustable, and comfortable seat for older children transitioning out of harness seats.

The Jovikids I-Size Booster Seat is well-suited for children aged 6 to 12 years, accommodating heights from 125cm to 150cm. It's designed to prioritize safety with an ECE R129 approval and a belt guide that ensures the car's seat belt is properly positioned on your child's shoulder. This adds a layer of reassurance for parents prioritizing safety standards.

Comfort-wise, it features a padded cover and armrests, which can make longer trips more enjoyable for your child. The seat's lightweight nature, at just 3 kilograms, and compact size make it a convenient choice for families who frequently switch the booster between vehicles, or for those who travel often. However, the seat is forward-facing only, which limits its use for younger children who might still require rear-facing seats for optimal safety.

The installation is via a seat belt, so while it fits various car models, it might not offer the same level of secure fit as some ISOFIX systems unless properly installed. With three height positions, it allows some adjustability, though more options might be desirable for a more tailored fit as your child grows. Maintenance is simple with a removable and washable cover, which is a practical feature for busy families. This seat is highly rated by customers, often praised for its reliability and comfort.

In conclusion, the Jovikids booster is a solid choice for parents looking for a comfortable, safe, and travel-friendly option for older children, though those seeking more advanced installation systems or rear-facing capabilities might need to consider other options.

The Maxi-Cosi Tanza i-Size booster car seat is designed to accommodate children from ages 3.5 to 12 years, supporting heights from 100 to 150 cm and weights up to 36 kg. This makes it a versatile choice for growing children, allowing for extended use through various stages of childhood. Its forward-facing orientation and ISOFIX installation provide a secure fit according to the latest EU safety standards, giving parents peace of mind. A standout feature is the G-CELL side impact protection, which helps protect your child's head, neck, and shoulders in the event of a side collision.

Comfort is also well-considered, with the seat offering 10 adjustable headrest positions, ensuring it can grow alongside your child. The padded seat and elevated design enhance your child’s comfort during car rides, allowing for a better view and a more enjoyable travel experience. The seat’s eco-friendly production is a thoughtful addition, featuring 100% recycled fabric covers that are machine washable, making maintenance straightforward.

The seat is relatively lightweight at 6.75 kg and features a compact, foldable design, which makes it easier to transport between vehicles or store when not in use. However, it's worth noting that the installation requires a seat belt, which might not be as quick as ISOFIX for some parents, especially when frequently moving the seat between cars. While the car seat scores highly in customer reviews, indicating a generally positive reception, the black color might not appeal to everyone seeking vibrant options.

In conclusion, the Maxi-Cosi Tanza i-Size is a strong contender in the booster seat market, balancing safety, comfort, and practicality effectively. It is particularly suited for families looking for a long-term car seat solution that maintains safety and eco-consciousness, though those frequently moving the seat might find the seat belt installation a slight inconvenience.
