10 Best Car Booster Seats 2025 in the UK

The Jovikids I-Size Booster Seat is designed for children between 125-150 cm in height and supports a weight range of 23 to 36 kilograms, making it suitable for kids aged 6-12 years. This forward-facing booster seat uses the car's 3-point adult belt for installation, which is generally straightforward but may require frequent adjustments to ensure proper fit. The inclusion of a belt guide is a significant safety feature, helping to correctly position the seatbelt on the child's shoulder and improving safety during travel. The booster seat also meets the stringent ECE R129 safety standard, further ensuring the reliability of the product in protecting your child during rides.

Comfort is well-addressed with features like a little armrest and a padded cover, making it a cozy option for long trips. However, the seat's compact design might be a bit tight for larger children within the stated age range. Another plus is the seat's lightweight and portability, which makes it an excellent choice for families who need to switch cars frequently or travel often. The seat's cover is removable and washable, facilitating easy maintenance and keeping the seat clean over time.

On the downside, some parents might find the lack of additional comfort features, like extra cushioning or adjustable headrests, less appealing for longer journeys. Additionally, its minimalistic design and lack of advanced adjustability might not meet the preferences of all users. The Jovikids I-Size Booster Seat is a reliable, comfortable, and convenient option for everyday use, particularly benefiting families who prioritize safety and ease of installation.

The Maxi-Cosi Tanza i-Size booster seat is designed for children aged 3.5 to 12 years, accommodating height ranges from 100 to 150 cm and weighing up to 36 kg. This high back booster seat is forward-facing and boasts a robust safety profile, including ISOFIX attachments and G-CELL side impact protection, aligning with the highest EU safety standards. These features ensure that the seat provides dependable protection as your child grows.

One of the standout aspects of the Tanza is its adjustability, offering 10 different headrest positions to cater to your child's growth over the years. The seat also prioritizes comfort with its padded design and elevated position, allowing children to enjoy better views during car journeys. Additionally, the seat is eco-friendly, utilizing fabrics made from recycled plastic bottles, which are skin-safe and machine washable for easy cleaning.

In terms of portability, the Tanza's compact foldable design makes it convenient for transfers between vehicles or for storage. However, the installation is seat belt-based, which might not be as quick or secure as some ISOFIX-only models for users who prefer a more straightforward setup. On the downside, at 6.75 kg, the seat is relatively lightweight for a high back booster, which may affect its stability. Despite its focus on eco-friendliness, some components are made of plastic, which might not appeal to those looking for more premium materials. These factors, coupled with a competitive price point, make the Maxi-Cosi Tanza i-Size an ideal choice for parents looking for a versatile, sustainable, and safety-conscious booster seat for everyday use.
