nice set, chairs are a pain to level
overall assembly was straight forward though - recommend a ratchet with hex bits vs the included wrenches
quality control could be a bit better - one of the chairs had an incomplete hole for the side bar to insert into (had to dremel it out in order to assemble it).

bad q&a info from wayfair (i've requested they correct to help others):
54x54 is WITH the leaf inserted (drop in leaf NOT desired butterfly)  
leaf is 12 inches so 42 x 54 without

Pros: overall quality
Cons: chair assembly/leveling
