We bought these sofas from M & S and have only had them a couple of months. I've been quite disappointed that the cushions look a bit stretched and creased when I was hoping they would maintain that crisp new look. They don't get loads of wear and tear (no kids, pets etc) so I'm looking for ideas of how we might make the cushions look a bit more full. I was wondering about getting some thin upholstery foam, cutting to size and putting inside the cushion cover to 'stretch' it a bit and make the fabric look more taught. Any clever folk out there with ideas ? I've included photos of the sofa that we sit on compared to the one that is used very little.
