The Axkid Up High Back Booster Car Seat is designed for children aged approximately 4 to 12 years old, covering a height range of 100-150cm and up to 50kg in weight. This high back booster seat offers a tailored fit for all children 4 to 12 years old and is certified up to 150 cm. The seat features adjustable seating height, removable side impact wings, and an adaptable headrest to ensure a perfect fit as your child grows.
What makes the Axkid Up unique is its patented raisable seat technology - the only high back booster seat in the world with a patented raisable seat. This HeightControl™ feature automatically positions your child at the optimal height to benefit from the car's safety systems, including side airbags, pretensioners, and optimal belt routing. While the seat can be used from 100cm, Axkid always recommends keeping children rear-facing for as long as possible, preferably up to 125cm (approximately 6-7 years), as rear-facing travel is significantly safer.
The long usability range means the Axkid Up adapts to your child's growth curve, offering excellent value for money and eliminating the need for multiple booster seat purchases as your child develops from preschool through to their teenage years.
I'd like to say using LittlePeas Shop has been a great experience and since that purchase I've also placed another order. Very quick shipping.
The seat itself is great - my son is 6yo, 120cm and 19kg and he finds it really comfortable. Especially fond of the foot rest. We chose the Axkid Up because of how narrow it is and when I remove one of the side protection panels, I can actually fit in the middle seat of an Audi Q5 between the Up and a BeSafe Beyond.
The other reason for our choice was the option to fold it and easily transport it, which we have not yet done, but we frequently fly, so that will come handy - we also got the transport bag.
Overall great purchase, can't fault the product or the service at all so far!

Firstly VERY quick postage. Item arrived well packaged too. Item itself quite heavy (but not much different to other car seats and has ISO fix base) but the way it's designed with the easy carry handle makes all the difference. Super easy to set up in the car, I love how easy it is to adjust the seat and backrest and the longevity of this car seat. I had a deal with footrest and carry bag. The carry bag is game changer for flights and just transport generally. I have previously had axkid mini kid and I know the safety record of axkid too. I will be purchasing another once my youngest is big enough. Very happy with this car seat.
