Globalkids I-Size High Back Booster
The Globalkids i-Size High Back Booster is designed to grow with your child. It complies with ECE R129 i-Size safety regulations, including side crash testing and protective materials in the head area. It transitions from a high-back booster to a tall backrest as your child reaches about 12 years old, spanning roughly 100 cm to 150 cm in height. Installation supports both Isofix and belt-fit options, with clear colour cues to avoid incorrect fitting. This model is suitable for children from approximately 3 to 12 years, weighing 15–36 kg.
Key features include easy installation, a cup holder, and an adjustable width to fit a variety of car interiors. The headrest and backrest adjust to accommodate growing shoulders and neck support, helping to maintain proper belt positioning and comfort on long trips. This seat balances safety standards with practical everyday use.
Fit and use considerations: If your vehicle has Isofix anchors, you can secure the seat quickly; otherwise, the belt installation remains straightforward. Ensure the red/green indicators are correctly aligned to confirm proper locking. Regular checks should be performed to ensure the headrest remains aligned with your child’s shoulders.
