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

Axkid ONE sets a new standard of car-seat safety. It is the only rear-facing ISOfix seat on the market that is i-Size approved up to 125 cm/23 kg, meaning your child can travel rear-facing for up to 2 years longer than in 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 marketThanks 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 builtin 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.

  5. Sliding seat for best legroom

    The Axkid ONE seat is mounted on rails that allows every parent and child to sit comfortably at all times and can be adjusted after the car seat has been installed. In one simple step, it is possible to provide the child with extended legroom when traveling in the car, or when not in use simply adjust to allow additional space for the front passenger.

  6. Sustainable and toxic-free materials

    Its protective safety shell and frame system is thoughtfully designed to achieve a range of strength, ductility, and toughness properties,meeting today´s safety regulations and environmental footprint reduction with the use of sustainable and toxic-free materials.

  7. Innovative lightweight design

    Inspired by aircraft engineering, Axkid One’s protective aluminium frame maintains the structure of the car seat while the high strength steel bars withstand and direct the forces of the impact away from the child’s body in the event of an accident. Axkid ONE weighs 30% less than a comparable car seat.

  8. Axkid Side Impact Protection

    As with all Axkid car seats, we have included our attachable side impact protection - ASIP. It has been developed together with a recognized crash institute in Germany, providing the best possible protection for the child in the event of a side-impact collision. ASIP should be used on the side of the car seat that is facing the car’s door. When using the car seat in the middle, ASIP is not required.
