Easy to assemble. 5-7 mins each chair. 
The chairs are a fair size. I'm 5"9 and my bf is 6"3 and we both fit well. 
7 out of 10 on the comfort part.
The package arrival was on time. 
Only down side: This chair is not Ivory color nor any thing near white. 
It's a refined cream and tan color. Good thing I did not buy all my other white decor yet!
