I have to say it depends on the sofa. I quite like black leather but can't stand those 70's type tweedy sofas with flowery patterns I imagine in a furious fight between Callum and one of those he may be marginally more interesting.

It's too close to call IMO.

I'd enjoy sitting on both

i like the red Knowle sofa in Downton Abbey i'd watch that sofa for days rather than 5 minutes of Callum
