The sex doll's skeleton is also a factor.

In the sex doll's body, beneath the velvety soft skin there is a premium EVO skeleton. Premium skeletons make it easy for the sex doll to assume more different positions and keep your favorite positions even during the wildest nights of love. To achieve this, the steel skeleton modeled after a human must be strong enough. Of course, this is associated with a higher weight.

As you have noticed, BBW sex dolls are the heaviest, because the material of the breasts and buttocks, as well as the movable steel frame, are all weighted. But it is sex dolls with this premium EVO skeleton that make sex with your lover realistic.
