Joie i-Trillo i-Size Booster Sea

The Joie i-Trillo i-Size Booster Seat is a lightweight high-back booster designed for children from 100cm to 150cm. Forward-facing and used with your car’s three-point seat belt, it offers practical safety, comfort and easy everyday fitting for growing children.

Approved to the latest ECE R129/03 safety standard, the Joie i-Trillo helps position the vehicle seat belt correctly across your child. Its high back provides support as your child grows, while the coloured belt guides make installation clear and straightforward for parents and grandparents alike.

The i-Trillo is an excellent choice when your child has outgrown their harnessed car seat but still needs the protection, support and correct seat-belt positioning provided by a high-back booster.

Joie i-Trillo i-Size Booster Seat: safety and support

The Joie i-Trillo i-Size Booster Seat features side-impact protection to help protect your child’s head, body and hips during a side collision. The high back and adjustable headrest help ensure the seat continues to fit well as your child gets taller.

A child should remain in a high-back booster seat until they reach 150cm, rather than moving too early to the adult vehicle seat alone. The high back helps keep the shoulder belt correctly positioned across the centre of the shoulder and the lap belt low over the upper thighs.

The Joie i-Trillo is used forward-facing with your car’s three-point seat belt. Its colour-coded belt guides make it easy to see where the seat belt should be placed, helping achieve a secure and correct fit on every journey.

Grows with your child

The one-hand, 10-position adjustable headrest makes it simple to adapt the Joie i-Trillo i-Size Booster Seat as your child grows. There is no need to rethread the seat belt or make complicated adjustments: simply raise the headrest to the correct height.

This makes the i-Trillo a practical choice for daily school runs, family trips and longer journeys. The supportive high back helps keep children comfortable while sleeping or relaxing in the car, while the headrest provides important head and neck support.

For family cars with more than one child seat, the slim design is particularly useful. It is designed to fit three i-Size boosters across the second row of compatible i-Size vehicles up to 135cm wide. Always check your vehicle handbook and ensure all seats can be fitted safely and independently before travelling with three seats across.

Everyday practical features

The Joie i-Trillo includes two practical cupholders, ideal for drinks, snacks or small travel essentials. When they are not needed, they tuck away neatly to keep the seat streamlined.

The covers are removable and machine washable, helping parents deal easily with spills, snack marks and everyday mess. This makes the booster a sensible option for busy family life.

Its compact dimensions and lightweight design also make it easier to move between cars when needed. However, for best safety, always ensure that the booster seat and vehicle seat belt are correctly fitted before every journey.

When is a high-back booster suitable?

The Joie i-Trillo i-Size Booster Seat is suitable once your child is between 100cm and 150cm tall. It is not suitable for babies or younger toddlers, and it does not use an internal harness.

A high-back booster should be selected according to your child’s height, not their age alone. Your child should stay in the seat until they reach the maximum 150cm height limit, or until the adult car seat belt fits them correctly without the booster.

The vehicle shoulder belt should sit across the middle of the shoulder, not against the neck or slipping off the shoulder. The lap belt should sit low across the top of the thighs, rather than across the stomach.

The Joie i-Trillo combines straightforward belt-guided fitting, adjustable support and everyday practicality, making it a reliable next-stage car seat for older children.
