I did not realize what we call a sofa is called a "Chesterfield". So I had to Google it; the first hit was Chesterfield County here in Virginia, next was some company selling a Chesterfield. I showed my wife the picture and she said "Nice sofa"!
It's a classic English brand of sofas. They are to leather couches what Hoover is to vacuum cleaners. I'd say 99% are dark leather. The one I posted would go better with the car in question. :)
