I hope i will get this scene some what good looking in the end.
Tried todo a leather material to the couch, but failed... any suggestions on what material that would fit better?
Personally I think the material you are using would be fine with less bump. It's more the model that look a bit "wrong" for a leather couch...it appears a bit "hard" if you know what I mean particularly the ends of the arm rests at the top. The curve from arm rest top to arm rest front seems unnaturally sharp.

You are right about the bumpyness, i did lower it many times, but it's just seams to be strong,
Changing the bump size B to it's lowest now.
What happends if i lower the bump map exponent?
