I saw the reviews about the manual, but took a chance I would get them. I didnt get them with the desk, but was able to track down someone through an internet search who could help.  
Wayfair customer service now has the manual for the desk too. So, if you are waiting on them or didnt get a copy with your desk, contact Wayfair customer service. 
As for the desk, it is great! We needed one that would go as low as 28. This one is perfect. It operates smoothly. My only complaint is that I wish I could have switched to have the longer side on the right instead of the left. (It was in the QA, I just didnt see it.)
