First of all, the general car seat cushion will have three locks, the lock button at the headrest, the lock button at the joint between the seat back and the seat, and the fixed lock button under the seat (some have fixed lock buttons on the left and right sides of the seat) . Basically most models will have a concealed slot under the seat to match the appropriate lock, so the first step to be done is to find the concealed slot under the seat and snap the bottom buckle of the car seat cushion to the concealed slot Inside, and then gradually fix each lock according to the shape of the car seat.

The seat back of the car seat and the seat are generally at right angles, and there is a gap at the joint. There will be a square buckle connected to the elastic band at the same position of the car seat. Just pass the square buckle flat through the gap, and then rotate 90 degrees to block the gap. Finished fixing the middle of the car seat.

The next thing to be solved is the fixation of the headrest (the headrest of the car seat with or without the headrest will have a fixed buckle). Some car seat headrests are equipped with an elastic sleeve. In that case, just put it on. There is also a buckle elastic belt like a seat belt.

The fixation method is the same as other places. The main thing is to "see the stitches", pass the elastic band in the gap of the headrest, then adjust the position of the headrest and buckle the buckle.
