Too stressful to couple! Can’t imagine I spent my precious over 20hours trying to put this together! Better off to include installation cost in the bill as an option. Far preferred than telling people it’s easy to couple together. I’ll rather pay someone else to install this and still come up with lots of errors on it. 
I was able to but it together in the end, it looks good in the room, but the time spent and the stress  doesn’t worth it
