360° rotatable for comfortable handling
With its practical 360° swivel function, the One 360 SL mini makes getting in and out of the car much easier. You can turn it towards the door with just one hand and strap your child in comfortably - without having to contort yourself. The shoulder straps can be fixed to the side with the help of magnetic holders and thus always remain within easy reach. The 5-point harness system automatically adjusts as your child grows - for more comfort and safety without additional effort.
Grows with your child & is comfortable at every stage
For optimum protection, the seat has an 8-point height-adjustable headrest with integrated slide protector. Depending on your child's height and stage of development, you can insert or remove the supplied comfort insert and head cushion. The seat shell is softly padded and shaped according to orthopaedic findings - for a comfortable sitting experience on both short and long journeys. The recline angle can be individually adjusted: 2 reclining positions in reboard mode and 4 sitting and resting positions in forward-facing mode.
Stable installation & tested safety
The One 360 SL mini is securely installed in the vehicle using Isofix and a height-adjustable base. Control indicators signal correct installation. The individually adjustable Isofix connectors ensure a perfect fit. In addition, side protectors increase safety in the event of a side impact. The seat is made of sturdy HDPE plastic and is equipped with an easy-care polyester cover that can be easily removed and machine washed at 30 °C.

• Please read these instructions carefully before use to ensure your child's safety. 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 weighing less than 18 kg and up to 105 cm in height.
• The child seat CANNOT be used with the 5-point harness system for children over 18 kg in weight and over 105 cm in height.
• The child seat can be installed rear-facing and forward-facing using the Isofix connectors and the support leg. When used 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 anchorage 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.

• 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 fixed in the vehicle even when no child is in the seat.
• Always ensure that all straps holding the child car seat in 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 objects that could cause injury in a collision must be properly secured.
• Rigid objects and plastic parts of a child restraint system must be positioned and installed so that they cannot be trapped by a moving seat or vehicle door.
• It is important that low-lying straps securely fix 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 consent 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 105 cm.
Never overload the child seat by carrying more than one child or additional loads.
• 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’s recommended cover, as this seat cover is an integral part of the restraint performance.
Remove all bags and packaging materials before use.
