I do love these chairs - great colour, sturdy, but I will rate them a 4 because the back gets quite narrow where it joins the seat. I am fine with it and it should be noted for larger bums. My husband is 6'1" and 206lbs and he just fits...
Would recommend!  

Pros: Sturdy, no assembly.
Cons: Narrow back with snug fit on the bottom back of the seat.
