Information about ScS The Sofa company?

I am attending an interview with this company. I always try to make sure I am well prepared, by collecting some information, eg when/where it started out, it's position in the market place, who it's founders were etc etc. But I cannot find anything except adverts, there is an FAQ but it only refers to customers questions about payment and delivery etc. Now this company is extremely well known here in the UK advertising almost nightly on the TV
