6) Place the chair frame and seat on top of the folding cardboard insert. The
boom of the chair should point toward the end of the box with the hand-
holes. Then, push the footplate receiver tube through the hole in the folding
cardboard insert.
7) Reattach the circular footplate clamp to the footplate receiver tube. If
your footplate clamp tightens via lever, like the one shown above, tighten
the lever. If your footplate clamp is tightened via an Allen key, tighten the
clamp so that it is secure on the footplate receiver tube.
