First of all, thank you to everyone who has taken the time to review this chair. 
This chair is a great buy.  It arrived in a carton especially designed for it.  So it was secure and had padding in places that the box might have rubbed on it.
The legs come in a zipper pouch on the bottom..Just take off the thread protector sleeve and screw in.  You have plastic washers that go on first....
Only issue I had was with some stray thread sticking out on the tufting.  I carefully snipped them off.  Applied A LOT of pressure to the seams...and they are holding just fine.  So it is minor and easily fixed.
Shipping was fast.
This is my 7th or 8th purchase from Wayfair.  I have yet to be let down.
