Chairs were pre-assembled, which was awesome!  Assembly was only for the table to add the legs and support bar.  The last step of the table assembly was confusing even though there were only 4 steps to the whole thing!  Anyways, the last step is to insert screws that didn't attach anything to the table.  The screws basically acted as stoppers against the support bar so it didn't move.  Fine, but he instructions could have been more clearer.  Other than that, the table and chairs were great.  We used it on our newly paved backyard patio and it was great because it was big enough to sit everyone and was very sturdy.
