I have only assembled one of these so far and I'm not pleased.  There aren't holes pre-drilled for several of the screws (at least, I couldn't find them, which either means they aren't there or the directions are terrible??)  And the wood was sounding like it was spliting....  I have no idea how long these are going to last.  They look nice from a distance, but hopefully no one particularly large tries to sit on them....  (I'm actually not worried about the seat holding up, but the cross bars seem weak and if people put their feet on them they might break.)
