There were two screws and two pegs.  The easiest assembly I have ever done (I was worried it would be more complicated.)  The chairs look great on our patio and are very comfortable.  The seat is pretty narrow, so you should order the larger chairs if you're not on the slim/average size. Overall, the chairs are much nicer than I expected; really good quality! (FYI the photo will only load sideways.)

Pros: Great quality, super easy assembly, true to design
Cons: none that I can think of
