Most listings show wiggle (wobble) discs with diameters around 13–13.5 inches (33–34 cm) and heights of about 2–3 inches. Example overall dimensions from listings include 3" x 12" x 13.3" or 2" x 13" x 13", varying by model.
Listings show wiggle discs made from PVC, foam, and rubber.
The search results list weights roughly between 5 and 6 ounces (one listing shows 5.62 ounces).
Some discs are textured; a few listings describe two-sided surfaces with large, spiky dimples on one side and much smaller dimples on the reverse to provide different tactile experiences.
Search results describe wiggle discs as suitable for both adults and children; some listings explicitly note adult use while others highlight classroom or therapy use for kids.
Many listings state discs ship inflated and include a hand pump for inflation adjustments; at least one title explicitly mentions a hand pump included in the package.
One listing gives specific steps: insert the pump pin through the valve to inflate, and insert the pin without the pump barrel to release air. The listing notes the valve is located on the fourth outer ring.
Some listings note a built-in handle to make the disc easier to carry.
No assembly is required; many items ship inflated or include a hand pump for quick inflation adjustments.
