Axkid Up i-Size High Back Booster Car Seat 100-150cm 4-12 Years

i-Size | Child Height: 100 to 150 cm | Age: 4-12 years approx. | Weight: Up to 50 kg

The Axkid Up is an advanced i-Size high-back booster seat designed to provide a tailored fit as your child grows from approximately 4 to 12 years old (100-150cm). Its innovative raisable seat helps achieve an optimal seatbelt position, while a solid steel frame, ISOFIX installation and integrated support leg provide additional stability.

Designed with growing families in mind, the Axkid Up combines long-lasting safety with everyday practicality. Its foldable QuickFold™ design makes installation, storage and moving the seat between cars easier, while ErgoSupport™ and a ventilated backrest help keep growing children supported and comfortable.

As children grow out of their harnessed car seat, correct vehicle seatbelt positioning becomes particularly important. The Axkid Up takes a different approach to traditional high-back boosters with its patented raisable seat, allowing the seating position to be adjusted as your child grows.

Suitable from 100 to 150cm and tested up to 50kg, the seat features an adjustable seating height, adaptable headrest and removable side-impact wings to create a more tailored fit for children between approximately 4 and 12 years old. Axkid states that its ProtecBase™ reduces crash forces by up to 25% in its internal crash tests compared with other booster seats.

The robust construction incorporates a solid steel frame and built-in support leg. When using ISOFIX, the support leg adds further stability. Alternatively, the booster can be installed using the vehicle seatbelt when required, giving families greater flexibility between suitable vehicles

Everyday usability has also been carefully considered. QuickFold™ allows the booster to fold down when it isn't being used and provides a clearer view of the ISOFIX connectors during installation. Its relatively narrow 43.5cm width can also make it suitable for families looking to accommodate multiple child seats, with Axkid stating that three Up seats can be installed side-by-side where vehicle compatibility allows.

For comfort, ErgoSupport™ has been inspired by Swedish school furniture to promote good posture and lumbar support, while ventilation holes in the backrest encourage airflow on longer journeys.

Important: Axkid recommends keeping children rear-facing for as long as possible, preferably until 125cm, before moving to a forward-facing booster seat.
