I got my corner sofa from Sofa Workshop in 2013 and it’s still going strong (although the shop has closed). I would say look out for special offers – mine was in the sale plus on the day I bought they were offering an extra 10% off. I got it on interest free credit and paid it over 12 months. Granted, things may be different now! I also have sofas from DFS and the quality just doesn’t compare, in my opinion it’s worth paying that bit extra for a sofa that will be more comfortable and last longer.
