Beyond joint placement, the strength and resistance of the joints are equally important. A well-designed sex doll must strike a balance between flexibility and firmness. If joints are too loose, the doll won’t hold a position; too stiff, and movement becomes impractical or even damaging. Manufacturers fine-tune joint tension to allow smooth transitions between poses while maintaining enough resistance to hold a posture without collapsing. Some premium sex dolls come with adjustable joint stiffness, allowing users to customize how flexible or rigid their doll should be.
