The Axkid Up is Axkid's most advanced high-back booster: a forward-facing i-Size seat for children from 100–150 cm (around 4–12 years, up to 50 kg), with a patented raisable seat, a steel base and a built-in support leg. Footrest included – new for 2026.
Free fitting when you buy from us – book a one-hour appointment in store and we'll fit the seat in your car and show you how to use it.
Delivery: £21 to UK mainland and Northern Ireland, or collect free from Towcester, Rayleigh or our Belfast fitting day – with free fitting included.
Is your child ready for a booster?
As extended rear-facing (ERF) specialists, we recommend keeping your child rear-facing for as long as possible – ideally to 125 cm. Not sure if it's time to move up? Ask us and we'll help you decide.
Will it fit my car?
The Axkid Up fits with ISOFIX and its built-in support leg, or with the car's seat belt. It's narrow enough for three in a row and can go in the middle seat. Call or email us with your car make, model and year and we'll check it for you – or book a free fitting appointment.
