Only six pieces- practically fool proof assembly.  Save the cardboard box to use as a work surface so the pieces do not get scratched by any rough surfaces during assembly.  Suggest two people, especially when pushing the hinges into the slots on the second to last step (we actually used blocks of wood and pipe clamps to gently persuade the last two of the three hinges into place one at a time- put an end hinge in FIRST).  We are using this to store Dahlia poles and other shorter gardening items over the winter.
