Unfortunately while the fit is true, the color IS NOT. 
I ordered Steel Blue, but when it showed on the site it looked light blue. In person, I thought they sent me teal. It is a DARK blue/green. The tag said steel blue and a friend of mine had ordered teal. She was sweet enough to bring one of her covers over to compare, and they were different. Her teal was darker than my Steel Blue cover, but not by much. 
The Steel Blue was only a slight bit lighter and definitely still teal. 
Also the covers LOOK like they are a solid color~ the squares of the elastic that run through them show UP, no matter the distance away. 
You are NOT buying a solid color cover, it looks busy with the elastic lines that are darker making tiny squares all over the cover. I looked from another room at the couch once the cover was on and I took still see the squares from pretty far away. I thought it would look like a solid color from far away but it doesn't. Very disappointed.
