According to North American market data, the annual sales growth rate of granny sex dolls is 67%, far exceeding other categories. Consumer surveys reveal the underlying motivation: 43% of buyers seek "non-threatening intimacy", and 27% use it as a tool to compensate for childhood emotional loss. To meet special needs, the size system of sex doll torsos has been expanded to XXXL specifications, and supporting elderly equipment manufacturers have even developed nursing brackets with a load-bearing capacity of 200kg. This demand change is reshaping the adult product industry chain.
