Has anyone bought a sofa from SofaSofa? Or recommend a company that makes well made good value sofas? (UK)?

I'm looking into getting a two piece suite, a sofa bed and another sofa and have come across SofaSofa (a href="http://www.sofasofa.co.uk)" rel="nofollow"http://www.sofasofa.co.uk)/a who do what sounds like good deals. Has anyone used them? Is the quality of the sofa's ok? I live near London so going to their shop in Cardiff is a bit of a way to go. Any other places that are worth looking at would be appreciated too, thanks.
