Flexible reboarder for maximum safety
The One360 SL reboarder from Osann accompanies your little passenger safely and comfortably from birth to school age. Suitable for children with a height of 40 to 150 cm, this reboarder covers the entire child seat requirement - a real all-rounder for many years to come. The 14-position height-adjustable headrest and the harness system that grows with your child ensure that your child is always seated safely and ergonomically.
Rear-facing for the best protection
For maximum safety, your child rides rear-facing up to a height of 105 cm - the safest position in the event of a frontal impact. From a height of 76 cm and a minimum age of 15 months, you can also use the seat in the direction of travel. Thanks to the Slide In protectors and widely protruding side flanks, the head and neck area is optimally protected, while the integrated head cushion and the comfort insert offer the little ones optimum support.
360° swivel function & clever handling
The practical 360° swivel function with the new EasyAdjust system allows you to switch effortlessly between the rear-facing and forward-facing position - with just one hand. When you sit in the seat, you simply fix the shoulder straps in place with the integrated magnets on the sides, so they don't get in the way and buckling up is even quicker. Two reboard positions and four adjustable sitting and resting positions in the direction of travel up to 125 cm ensure relaxed travel.
Simple & safe installation
The One360 SL is installed securely in the vehicle in accordance with the current i-Size standard using Isofix and a stable base. A green indicator shows you when everything is correctly locked in place. From a height of 100 cm, you can also use the seat with your car's 3-point harness; the base is then no longer required. The integrated 5-point harness system can be stowed directly in the seat if required - without having to remove it.

WARN- & SAFETY INSTRUCTIONS
WARNING!
• Please read these instructions carefully before use to ensure the safety of your child. Keep the instructions. Failure to follow the instructions in this manual may result in serious injury to your child.
• The child seat can only be used with its own 5-point harness system for children under a body weight of 18 kg and a height up to 105 cm.
• The child seat CANNOT be used with the 5-point harness system for children over a body weight of 18 kg and a height over 105 cm.
• The child seat can be installed rear-facing and forward-facing with the Isofix connectors and the support leg. For use with the support leg, the maximum height is 105 cm and the maximum weight is 18 kg. Important: Do not install forward-facing before the child is older than 15 months.
• For Isofix installation: Make sure to read the car manufacturer’s manual.
• Do not use any other load-bearing contact points than those described in the instructions and marked on the child restraint system.
• Do not use this child car seat at home. It is designed exclusively for use in a car.
• Never leave your child unattended in the seat.
• Do not place the rear-facing child car seat on a front seat with an activated airbag. This can cause serious injury or death.
• The child seat must be replaced if it has been subjected to severe stress in an accident.
• For safety reasons, the child car seat must be secured in the vehicle even if no child is in the child car seat.
• Always ensure that all straps holding the child car seat to the vehicle are tight and all straps restraining the child are adjusted to the child’s body. Also ensure that the straps are not twisted.
• Luggage or other items that could cause injury in a collision must be properly secured.
• Rigid objects and plastic parts of a child restraint system must be placed and installed so that they cannot be trapped by a movable seat or a vehicle door.
• It is important that low-positioned straps firmly secure the child’s pelvis. To avoid the risk of falling, your child should always be strapped in.
• It is dangerous to make changes or additions to the product without the approval of the competent authority. Failure to follow the installation instructions of the child restraint system manufacturer also poses risks to your child’s safety.
• This child seat is designed for children with a maximum height of 150 cm.
Never overload the child seat by carrying more than one child or additional loads in it.
• The child restraint system must not be used without the seat cover.
• The seat cover must not be replaced by any other than the manufacturer-recommended cover, as this seat cover is an integral part of the restraint performance.
Remove all bags and packaging materials before use.
