If, at some point, you decide you want to redo the sofa cushions with leather, consider good quality vinyl. One of our dogs intentionally and inadvertently ripped a couple of the leather cushions on our previous sofa. Took them to the upholsterer for repair. Was going to have them do leather, but as you said - quite cost prohibitive. They showed me some vinyl samples that were perfect. They fixed the cushions and you would never have known the difference. Color and texture were perfect and the cost was more than reasonable.
