Osann One 360 SL R129 i-Size Car Seat – Iron Grey

Description

The Osann One 360 SL R129 i-Size Car Seat in Iron Grey is an all-in-one, 360° rotating car seat designed to protect and support your child from birth until approximately 12 years old. Suitable from 40–150cm, this long-lasting car seat covers the key stages of your child’s car travel, from newborn to high-back booster.

Approved to the latest ECE R129 i-Size safety standard, the Osann One 360 SL offers families an excellent combination of safety, comfort and everyday practicality. It has undergone additional testing to ADAC-level standards, giving parents extra reassurance when choosing a car seat that will be used for many years.

The elegant Iron Grey finish is smart, neutral and practical for everyday family life. With soft, deeply padded fabrics and extra cushioning around the headrest, the seat keeps children comfortable on short trips, school runs and longer journeys.

360° Rotation for Easier Everyday Use

The Osann One 360 SL R129 i-Size Car Seat rotates a full 360°, allowing you to turn your child towards the car door when getting them in or out. This makes buckling up simpler and more comfortable, particularly during the newborn and toddler stages.

The Easy Adjust System allows rotation and seat-position changes using one hand. Magnetic shoulder-belt holders keep the harness straps out of the way while you place your child in the seat, helping to avoid twisting, tangling and fiddling with straps.

Extended Rear-Facing Safety

The Osann One 360 SL can be used rear-facing from birth to 105cm, with a maximum child weight of 18kg. This is approximately up to four years of age. Rear-facing travel provides enhanced protection for a young child’s head, neck and spine, so we recommend keeping your child rear-facing for as long as possible.

There are two rear-facing recline positions to support your child as they grow:

• Position R1: 40–75cm
• Position R2: 76–105cm

Your child may travel forward-facing from 76cm and at least 15 months old. However, remaining rear-facing until 105cm is the safer option whenever possible.

One Car Seat From Birth to 12 Years

This adaptable Osann One 360 SL R129 i-Size Car Seat grows with your child through three important travel stages. The 14-position adjustable headrest provides support as your child gets taller, while the five-point harness automatically adjusts with the headrest to help maintain a secure fit.

For newborns and smaller babies, the removable comfort insert and additional head-support cushion provide extra support. As your child grows, these can be removed to create more space and comfort.

From 100–150cm, the car seat easily converts into a high-back booster. The five-point harness stores neatly inside the seat, so there is no need to remove or lose parts. In booster mode, your child uses the car’s three-point seat belt. A crotch strap helps guide the vehicle belt into the correct position for a secure, comfortable fit.

Secure Isofix Installation

The Osann One 360 SL R129 i-Size Car Seat is installed using Isofix connectors and a support leg. The Isofix connectors are individually adjustable for a secure fit in your car, while the support leg provides extra stability.

An additional slide protector adds increased side-impact protection, helping to protect your child in the event of a side collision. The seat also has four forward-facing sitting and reclining positions, available up to 125cm, helping your child travel comfortably as they grow.

For clear fitting guidance, always follow the car seat instruction manual and check your vehicle handbook to confirm compatibility.
