This is a well engineered product to a degree.  I found the greatest grievance with the hardware.  The pegs were not snug in the holes. Several of the pre-drilled holes were misaligned.  To add insult to injury, there were two pieces in my box that should have been pre-drilled but were not. . As a general premise the whole thing difficult to put together. The instructions are not well drawn.  (I draw CAD documents for a living.)
