thanks Bill, all concepts help me decide the best way to proceed.

Here's another couch question. On 390 the seat and backs were at a comfortable seating angle. On 512, the seat is angled upward at the front edge and the back is straight up with no incline. I suppose when I take the couch out, I'll understand if the jack knife mechanism can be adjusted to compensate. I have notice other Villa sofas in the more recent coaches are more of the upright back.
