The middle upright metal posts are bent out a little at the top, making exact alighment with the overhead crossbar impossible.  The corners of that upright stick out a little.  Could someone hurt their hand on that?? However, I am not sending it back.  the instructions for assembly (which requires 2 people) are clear and all  needed for assembly was included.  The delivery was earlier than Wayfair said which made life complicated.  Overall, though, the item is very sturdy and easy to handle.  Also Wayfair was easy to do business with.
