SCS will tell you anything to get the sale! I bought a suite believing that the whole suite was under guarantee.... Horrified to find that when my cushions sagged the estimate for a repair was over £600. The guarantee does not cover the cushions and its your word against ours was the reply I got when I dared to question them! Of course they are not members of the furniture ombudsman so your options are limited...it's all on their terms. They told me to pay them £75 for one of their team to inspect my furniture and decide if it's fit for purpose. Even if it's not they keep my £75 but will repair as necessary. Their decision is final!
My advice buy from an honest reputable company who, if there is a problem, will allow you to refer to the sale of goods act and get an independent appraisal....I've certainly learned my lesson.
