Them Bones Outdoor Playset 

Them Bones is an outdoor playset concept incorporating modular vertebrae which allow the unit to "grow". The structure provides attachment points for accessories as well as additional customization.

The head's for hiding, the tail's for sliding. Ribs anchor the structure to posts buried in the ground.

Head and tail are rotationally-molded polyethylene; ribs and vertebrae are blow-molded with strengthening inserts.
