Note: 
    Since this product is inflatable, the air pression outside is less than the air pression inside of the built-in air bag. It will slowly deflate with pressure like a balloon, and it is impossible to keep full filled in a long time. Therefore, if the airbag is not full after a few hours' compression during use, it's normal and it just needs to be inflated again.
   Please understand that this is a physical problem, not a quality issue of the product
