I have to admit I was a little apprehensive on the purchase of this piece.  Most of the reviews were talking about how difficult it was to put together, but I am very please with the piece and glad I bought it.  I do have to say, it does take 2 people to put it together.  working from the bottom up, you need extra hands to hold the legs together while the other person tightens the bolts.  The instructs are very small and hard to see the pictures.  use the washers and lock nuts with each screw.  DO NOT tighten the screws on the back until after you have the arms in placed and screwed in.  You will need the flex on the back in order to get the arms in.  My husband and I both worked on it one night and had it done in about an hour.  It really doesn't have that many pieces.  
Love it!!!
