A playground base and standard assembly (10) includes a typical hollow traffic cone (28) having a top hole (20) for receiving a standard (12) into the cone (28). The cone (28) is modified by placing an insert (26) inside the cone for stabilizing the standard (12). The insert (26) is a solid polyethylene foam member shaped to fit snugly in the cone (28). The insert (26) has a hole (34) coaxial with a top hole (20) on the cone (28) for receiving and supporting any standard (12). One possible standard (12) includes telescoping members (40,42) for adjusting the height of the standard.
