I LOVE this set.  I bought the Cilantro color.  It's such a different color.  
The directions for putting the cushion covers on say to take off the beige ones (the beige ones come with the set and are already on the cushions).  I put the green ones right over the beige.  It was so much easier than removing the beige and then trying to put the green on.  
I also bought the medium clip set to hold the sectional pieces together.
