This dense safety net is suitable for round trampoline frames with 6 straight posts. Due to its weather resistance, it can be used both indoors and outdoors. This net is made of durable PE, which is non-toxic and can be firmly attached to the frame. The excellent workmanship guarantees long-term use. The PE net can be securely connected to the trampoline. Due to the height of 180cm, children cannot jump over it. So you don't have to worry about safety.
