Introducing Axkid ONE – A new generation rear-facing car seats with ISOFIX 

Axkid ONE sets a new standard of car-seat safety with ISOfix. It is the only rear-facing ISOFIX seat on the market that is i–Size approved up to 125 cm/23 kg. It is also the only car seat on the market with these maximum limits to pass the Plus-Test and its high demands on crash safety. These conditions allow your child to ride rearwards and safely for up to 2 years longer than existing ISOFIX seats on the market. Traveling rear-facing is up to 5 times safer for children all the way up to 6-7 years of age.

Strong and lightweight design innovated in Sweden 

Axkid ONE is built with a new and innovative design that uses aluminum and hardened steel to form a lightweight safety frame that acts like a protective cocoon. The seat itself is built in shock-absorbing materials to minimize crash-forces upon impact. We also added ventilation holes in the seat to keep your child cool during the hot summer months. The whole seat weighs less than 10 kg allowing older and heavier children to travel rearward all the way up to 7 years of age. 

Best legroom on the market 

The Axkid ONE is mounted on rails (pat. pending) allowing the seat to be adjusted back and forth with just one hand up to 30 cm. This unique feature solves the past drawbacks with rear-facing seats. It is easier to install your child into the seat as the angle is wider. For older children the safety frame can act as a handle so they easily can climb in and out themselves. No need for swivel functions. Older children can travel comfortably up to 7 years or 125 cm and the oversize design of the anti-rotation bar means that they gain extra legroom compared to other seats in the market. Thanks to the rail-mounting it’s easy to give the front seat passenger extra space when needed without removing the seat from the car, just push back the seat towards the back seat. No other seat on the market has these features. 

Quick and secure installation in 30 seconds 

Many car seats, both forward-facing and rearward facing is to some extent installed incorrectly, impeding the safety of the seat. Therefore Axkid ONE features 6 self-explanatory installation steps and a self-tightening anti-rotation bar with a built–in audio cue telling you if the seat is in optimal position. Combined with ISOfix connectors and the lightweight construction which makes handling easy, we guarantee that you can install the seat in less than 30 seconds. 

Comfort from 0-7 years of age 

Axkid ONE comes equipped with the Sleepwell System allowing the seat angle to be adjusted all the way to 42 degrees. This means that Axkid ONE can be tilted to act as an infant carrier with the ONE+ cushion the first months. Also, older children will appreciate the angle and easier fall asleep on the road trip. 

Axkid One+

With the soft inlays as extra support and the possibility to adjust the seat angle, your infant can travel safely in this seat from day one (sold separately).
