Axkid UP High Back Booster Car Seat with Footrest - Mist Grey

Axkid UP i-Size High Back Booster Seat with Adjustable Seat Height

Designed for growing children from 100–150cm, the Axkid UP combines an adjustable seat and backrest to help achieve correct seat belt positioning. Flexible installation, compact folding and an included footrest make it practical for everyday family travel.

Product Description

The Axkid UP takes a different approach to booster seating: rather than adjusting only the headrest, its HeightControl™ system also raises the seat. This lets you tailor your child's sitting height and belt alignment as they grow.

A reinforced steel ProtecBase™ incorporates ISOFIX connectors and a support leg for added stability. The vehicle's three-point seat belt secures your child in every installation mode, with belt-only fitting available where suitable ISOFIX points are unavailable.

QuickFold™ folds the backrest down for easier storage and transfer between vehicles. ErgoSupport™ provides built-in lumbar support, while a ventilated backrest helps maintain comfort on longer journeys.
