ABSTRACT:
A scaffold structure comprising a tubular column positioned vertically in use by a base support for supporting a base end portion of the column. Top supporting structure supports a top end portion of the tubular column and is effective to maintain the column vertical in use. The base support and top support impart torsional rigidity to the tubular column. A positionable platform assembly having a platform for standing thereon is positionably mounted on the column for positioning the platform at a selected height above the base end of the column, and to permit adjustment of the height of the platform above the base end of the tubular column.
