We are looking at Stickley-Craftsman, Century, Hancock-Moore, and Legacy Leather. I have MS and it is imperative that we purchase a firm cushion sofa whose seat cushions can be rotated. We are looking for a 95 inch sofa. I am interested in what leather fabric grade from each should last for 10+ years. We have looked at the following styles: H-M Evening sofa, Legacy Leather -Nelson, Stickley-Santa Fe. I appreciate your quick feedback.
