In spite of the fact that the holes on the chair seats were drilled in the wrong places, our son-in-law assembled everything quickly because he is savvy about such things and brought a drill with him.  If it had been us, we'd have had to send the set back.  It looks nice but hasn't been put into use yet so can't speak for quality or functionality.  No information on weight restrictions on the chairs.  Still the right size for our down-sized living.
