A wonderful giant top for hours of fun. Top for 1 or 2 children. Lots of uses: use it to rock from side to side spin it build a den etc. Small children can even use it as a boat in the pool (only under adult supervision). Develops children s physical coordination while they play. Made of strong plastic for both indoor and outdoor play. Very suitable for basic physical coordination training with disabled people. Take a good look at our original top. Only the original top is shaped with a pointed center. This enables children to get the feeling of turning upside-down when moving the top 360 degrees around the center. The edge of the top protects children s heads and hands from getting hurt. Raised edges prevent children from getting their fingers caught under the top. At the same time there is no risk of suffocation if children hide inside the top. 3-10 years.
