Joie i-Trillo i-Size R129 Belted Booster Car Seat
The Joie i-Trillo i-Size Belted Booster Car Seat is a forward-facing seat designed to keep children aged approximately 4 to 12 years safe and comfortable across years of family journeys. Certified to the latest R129 i-Size standard, it meets rigorous crash-test requirements and includes reinforced side-impact protection wings that wrap around the head and torso — giving parents genuine, verified reassurance rather than a marketing promise. Colour-coded belt guides direct your car's 3-point seatbelt into exactly the right position every time, removing guesswork during busy school-run mornings. The headrest adjusts across 10 positions with one hand, so you can fine-tune the fit as your child grows from 100 cm to 150 cm tall without removing the seat from the car. At 4.43 kg, the seat is light enough to move between vehicles with ease, and the cover unzips for machine washing — useful after long road trips or the inevitable snack spills. A single-position recline lets children rest comfortably on longer drives. Suited to children weighing 15–36 kg, the i-Trillo is a seat your family can rely on from nursery pick-ups right through to secondary school. Pair it with a Joie travel bag to protect it on flights or during boot storage.
