Here is the bench that dad built. Isn't it beautiful? The first picture shows the complicated infrastructure and the last shows how wonderful it is. It has an inside floor, piano hinge and is long enough for the husband to lay across. I have to squinch up a bit, but it is possible.
My dad filled the holes and next we will prime and then paint it. I haven't decided on a color (you know about me and paint color selection), but am leaning towards something simple - white perhaps? I then have to get some foam and fabric (you know about me and fabric selection) to make cushions for the top. Then, it is tush ready (or tail ready as I think Sahale might be excited to see we built her a HUGE dog bed).
