I wanted black frame  with dark cushions.  The cushions have a little bit of a color weave to them which makes them look very dark charcoal or off black.  Adds depth instead of pure black.  My neighbors remarked how they liked the clean, modern look that usually only accompanies the very large, very expensive furniture.
It was very easy to assemble, all holes lining up perfectly, all parts present. Does not even require 2 people.
You don't sink into the cushions.  They support you!!!
