First, the pieces were dirty and smelled badly.  Every piece had to be wiped down before assembling.  It was like the parts had been laying on a warehouse shelf for years.  

The instruction set was incorrect.  There were missing screws (there was suppose to be a package 'I' and they did not exist.  There were extra 'C' screws that worked, but one short for everything that was needed.   

Several of the drill holes were not at the right depth and connecting the two of the connecting bolts was very difficult.     

The whole assembly process took too long and was too frustrating.   This was not the Wayfair quality that we are use to or expected.
