Double slides, the design idea is derived from grass sliding. The child pulls the air cushion, walks to the entrance of the slide, and sits on it. The air cushion will rotate slightly when sliding, bringing greater stimulation to sliding. You need to remain calm and hold the handle with both hands until you hit the ground. During the sliding process, the child needs to maintain balance and the waist should be straight, which can train the child’s sense of balance and enhance the understanding of space during sliding.
