To use as steps, lift the top tread and find the hinged step riser underneath it.
Raise the step riser and insert it into one of the two slots on the underside of the tread.
Make sure the step is level; if not, move the step riser to the other slot on the underside
of the tread.
Set up the middle step and then the bottom step in the same manner. Always work from
top to bottom when setting up the steps.
