Today, one year later, we found one in Leon's that looked good in that respect. The seating width is similar to our current, old loveseat. However, this image is the full size model and it's a full 10" wider than where I'm typing this. It won't fit in our small apartment. And it seems a loveseat version of this would offer far too little space on which to sit.
So we have to find something nearly similar in size to what we have. It can be only 72" wide but the cushions should offer about 60" of butt space. A replacement doesn't need to offer sleeping options. Now we're not even sure it must be leather. It simply must look better than this old green cloth thing that turns twenty years old next summer. Hopefully, we'll have something new before then!
