The Ultimate Guide to Sex Doll Skeletons
The skeleton is the foundation of any realistic sex doll. Without it, the doll would be just a jelly-like lump of silicone or TPE.
Standard Skeleton
The simplest type — metal tubes welded together. It's the most commonly found in counterfeit models.
What it can do: Basic movements — head, arms, waist, and legs. Can stand independently and take basic poses.
What it can't do: Torso twists, limb bending beyond 90 degrees, complex head turns, or shoulder lifts.
Upgraded Skeleton (EVO / EXP / Flexi / Yoga)
Most brands call this EVO (evolution), but names like "Flexi," "Yoga," or "EXP" are also common. These are significantly improved versions of standard skeletons.
What it can do: Much wider range of movements, smoother bending, greater angles, shoulder joints that let the doll raise its shoulders, and even complex positions like lotus pose.

Verdict: Always choose the upgraded skeleton. It's relatively inexpensive but offers many advantages.
