The Kinderkraft I-BOOST 2 PRO i-Size is a premium booster car seat designed to provide enhanced safety, comfort, and practicality for growing children. It is suitable for children with a height of 125–150 cm (about 6–12 years old) and meets the latest European R129 i-Size safety standard, which includes strict crash-test requirements to ensure high protection in real-world conditions.
This model features stable ISOFIX installation, making it fast and secure to fit in most cars and reducing installation errors. The ergonomic design includes a wide, soft seat with foam cushioning and ergonomic armrests to keep your child comfortable on both short trips and long journeys. Practical belt guides help position the car’s 3-point seat belt correctly across the child’s shoulder and chest, improving safety and stability.
For added comfort, the seat uses a breathable AIR FLOW 3D mesh fabric that improves air circulation, keeping your child cool and comfortable throughout the ride. Despite its robust build, the booster is compact and exceptionally lightweight (about 2.36 kg), making it easy to move between vehicles. The removable, machine-washable cover ensures simple everyday maintenance.
