Piece fit our needs and went together quickly.  

I would suggest using a rubber mallet assist in putting the  four cam locks (part G1) into place,  and 1/2 inch socket  with extension bar to fasten the eight bolts (part J).

I assembled this piece by myself, placing the top on a workbench and using the corrugated  box cover that it was packed in as the second set of hands.  I cut four notches in the side of the box that were about 7 3/8" from the top.  The notches were 2" wide and the space between ~13".  The box cover was then slotted over the bottom of  the table top (see Instructions page 3, illustration 1).  I reinforced the ends of the box with packing tape to make sure it wouldn't collapse.  Lower shelf (part B) was then very easily installed following the  assembly instructions.
