The material of the air bed is somewhat elastic,but don't get too pumped. 3.When the temperature drops,the air mattress will become soft,so pay attention to replenishing air.When the temperature rises,pay attention to let out some air. Keep away from flames and high-temperature items and avoid prolonged exposure to sunlight, as excessive heat can cause the air mattress to overinflate and damage it. 4.It should not be too full at any time when inflating,otherwise the pull straps in the bed may be over-loaded and broken,resulting in a bulge on the bed surface, which cannot be repaired. 5.Avoid using sharp tools or knives that may scratch the fabric. 7.Do not use it as a floatation device. 8.Ensure the air pump is stored in a dry and non-humid environment.
