Certified safety and unlimited comfort guarantee a great trip. ONETO3 i-Size, which is compliant with the latest R129 i-Size standard for car seats, has been created with young passengers in mind. It’s designed for children from 76 to 150 cm tall (from 15 months to approximately 12 years).

The car seat features the ISOFIX system and TOP TETHER strap, guaranteeing easy and correct installation in the car. It’s equipped with dedicated safety systems, such as the SIDE PROTECT SYSTEM, which provides additional protection in the event of a side-on collision, as well as the H-GUARD SYSTEM, which is a three-layered, reinforced headrest that protects the child's head and neck in an accident. It's a car seat that will protect your little one for many years.

i-Size Standard

The ONETO3 i-Size car seat meets the requirements of the latest R129 i-Size standard. You can have peace of mind that your child is safe and therefore focus on driving the car. ONETO3 i-Size is the successor of the iconic ONETO3 model, which achieved a high ADAC rating.

Highest level of safety

The high, reinforced side protection (SPS) absorbs energy created in a side-on collision and doesn't allow it to reach your child. It protects your youngster’s shoulders and hips in the event of an accident. Protection is ensured by the H-GUARD SYSTEM, which is a three-layered memory foam headrest that absorbs energy and disperses it thanks to the layers, not allowing it to reach sensitive body parts.

Easy ISOFIX installation

The car seat can be installed in your car in just a few moments, thanks to ISOFIX. When driving younger children, you must also affix it using the TOP TETHER strap. Both systems feature indicators to ensure correct installation. Older children can optionally travel in a car without ISOFIX connectors.

RECLINING function

The car seat is integrated with the base, meaning the angle of incline can be adjusted relative to the car's bench seat – you can do this using one hand throughout the entire period of use. You can easily set the car seat in one of five positions. This improves not only your child's comfort but also their safety.

EASY GROW SYSTEM

The headrest can be adjusted to 18 levels. The EASY GROW SYSTEM allows you to adjust the headrest and safety harness at the same time using one hand. Remember that a correctly adjusted headrest increases your child’s safety in the event of a collision! The safety harness can be put away in the seat once your youngster is old enough to use the car seat belt.

Removable insert

To ensure the comfort of little passengers, the ONETO3 i-Size car seat has been equipped with a removable insert for young children. It ensures comfort and decreases the distance between the child’s body and the car seat, increasing safety. The insert can be removed at any time.

Comfort on long trips

ONETO3 i-Size has a comfortable, wide seat, and the cover is made of safe materials that are pleasant to the touch. It can be machine washed, meaning it’ll remain fresh and clean for longer. This car seat also provides convenience for the parent – it has safety harness hooks on the side, which makes it easier to put the child into the car seat.
