When purchased the chair comes in it's profile state seen below.  All ofthe wooden support structure of the chair comes contained inside theABS housing as to cut down on packaging material.  The inside panelsare removed to access the wood panels and then are slid and fitted intoplace.  Screwing the inside panels back prevents the wooden support structure from moving.
