Our rugged buoy ball becomes the coolest seat on the playground with the addition of our high quality trapeze bar with rings (sold seperately).  The buoy ball attaches to any of our trapeze bars with two snap hooks (included).  The buoy ball can also be adapted to hang alone without a trapeze bar too.  Simply add more chain to the piece and it becomes a ride unto itself!  Kids will find all types of play uses for this great item...only their imagination can hold them back!  Ages 2-12.  Green balls, or traditional orange.
