Axkid One 3 is a rear-facing car seat developed in Sweden, designed to support children as they grow. With long-term usability, thoughtful adjustability, and a calm approach to everyday use, it offers a reliable solution for family travel. Built around a clear safety philosophy, Axkid One 3 is designed to feel reassuring from the first ride and for years to come.

Safety: Designed with safety at the core

Axkid One 3 is developed with a strong focus on protecting children, built on Sweden’s long-standing approach to child safety. The seat is created to support rear-facing travel and to help manage forces that occur during everyday driving situations. This model is intended to be used consistently and according to the instructions provided in the product manual.

Longevity: 10 Years of Use

Axkid One 3 is designed to support rear-facing travel over an extended period as a child grows. The seat accommodates rear-facing use for children up to 7 years old, 49 inches, and 65 lb, allowing families to use the same seat over an extended period of time.

With an intended product lifespan of up to 10 years, Axkid One 3 is built to be used over many years and stages of childhood. This long service life helps ensure the seat remains a reliable part of the family’s everyday travel for years to come.

Handling: Adaptable & Easy to Handle

Axkid One 3 is designed to be easy to use in everyday life. Straightforward adjustments allow parents to adapt the seat as their child grows, without adding unnecessary complexity.

The harness and headrest adjust smoothly to support your child and with the adjustable legroom of up to approximately 12 inches adds flexibility over time. This helps make every day handling simple and manageable for families.

Installation: Smooth Installation

Axkid One 3 is designed to support a controlled installation process. Clear visual indicators on the seat help guide positioning and provide reassurance during setup.

One 3 supports installation using rigid LATCH, which is the recommended installation method. Different installation methods support different child sizes and use ranges.

Always follow the instructions and guidance provided in the product manual to ensure the correct setup for your vehicle and chosen installation method.

Design: Easy Access

Axkid One 3 features a clean, purposeful design built around everyday use. The open seat design and solid frame can make it easier for older children to climb in and out more easily, supporting growing independence over time.

An integrated load leg is part of the seat’s overall structure, reflecting a Scandinavian design approach where stability and long-term use are central considerations.

The color palette is inspired by Swedish nature, with calm, understated tones designed to blend naturally into a wide range of vehicle interiors.

Comfort: Supportive Comfort

Axkid One 3 is created to make every ride more comfortable for children at every stage. A softly padded seating area with memory foam provides a supportive, cushioned feel that helps children stay comfortable whether the trip is short or stretches a little longer.

For younger children, a toddler insert is included to provide a snug and comfortable fit. This insert must be used for children weighing from 11 lb to 30 lb, as specified in the product instructions.

For the smallest children, an infant insert is required for use from 5 lb to 11 lb. The infant insert is sold separately and does not come included with the seat.
