Is the car inflatable bed safe?

Personally feel unsafe. The disadvantages of air mattress are: 1. Because air mattress is made of PVC material, this material will have certain ductility with the extension of use time or the greater the weight it bears, that is to say, the bed will expand, so it must be inflated in time, otherwise it will feel very tired when sleeping, and it is also harmful to the body; 2. Because the air mattress is made of PVC, it is necessary to avoid piercing sharp metal and not to let high-temperature objects get too close, otherwise it will be damaged and need your maintenance; 3. If it's a small beer, it's OK. I can finish the repair myself. If it is damaged in a large area, it is basically unusable, which is equivalent to scrapping.
