Hi. I have had one Nevada 2-seater sofa (from The Warehouse) for some years now, and unfortunately, one of the seaters is with a protruding spring. Is it possible to repair or change the stuffing or even buy a new cushion seater to replace it? The sofa is still in excellent condition, so I would prefer to fix it rather than discard it. Does your company do this kind of service? If yes, how much would it cost? Thanks heaps.
