Comfort & safety for your child
The Up i-Size booster seat from Osann is ideal for children aged approx. 7 to 12 years (125 to 150 cm tall) and offers your child a raised seating position to enjoy the best view on outings. The practical booster seat is easily installed using the car's 3-point harness and provides a secure hold. It has been tested and approved in accordance with the latest i-Size child seat standard ECE R129/03. As the booster seat does not take up much space in the car, several can be used next to each other or you simply have more space for other things.
The ergonomically shaped seat and comfortable armrests ensure a pleasant driving experience. A side mesh pocket can be used to store a drink or snack for the journey. The belt guide ensures that the belt runs safely and correctly so that your child is always well protected. The seat cover is easy to remove and can be washed at 30 °C, making it particularly easy to care for. Thanks to the robust plastic core, the booster seat offers safety and stability. The Up booster seat weighs just 1.1 kg and fits in all standard cars, which means it can be moved quickly between different cars.

• 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 when no child is in the child car seat.

• Luggage or other items that could cause injury in the event of 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 movable seat or vehicle door.
