This is a child and junior seat from the JoieTrip series made by COMBI. The usage conditions are as follows: Child Mode: 9-18kg Height 70-105cm, approximately 1-4 years old Junior Mode: 15-25kg Height 95-120cm, approximately 3-7 years old Booster Mode: 15-36kg Height 95-145cm, approximately 3-11 years old The cover can be removed and washed. It will be shipped after home cleaning. The overall bright color and mesh back make it easy to release heat, and it can be used for a long time. I used it only when I rented a car, as I didn't have my own car. This is a used item and has been stored at home, so please understand before purchasing. The original box is not available, so it will be shipped in a separate cardboard box. There is no instruction manual, but you should be able to view it online.
