ABSTRACT:
An article of play apparatus is provided having an open-ended, hollow rotatable member which is maintained in an elevated, horizontal orientation by two support members located one at each longitudinal end of the rotatable member. A plurality of padded ridges extend along the longitudinal extent of the rotatable member. In this manner, children can climb through the rotatable member while other children climb over it, causing the rotatable member to rotate. A novel bearing system is housed inside each support member.
