The mattress itself has two chambers, with a single trachea using a single chamber. Dual air pipes use dual chambers. Using another chamber, the air mattress works continuously through an air pump for a long time to inflate and exhaust, achieving a fluctuating effect. Two chambers circulate for exhaust and inflation. When a single chamber is deflated, the air pump will automatically change air after a few minutes, becoming a double chamber deflated, and the single chamber is full, constantly changing the area of force on the human body.
