Booth's Stairs

That is likely where Ms. Harris sat. The angle Bill took the picture at does not show the Lincoln rocker. But you can see the original chair Mary Lincoln occupied.

I don't remember that Clara Harris sat on an upholstered chair. I believe she was on a straight-back, just like Mrs. Lincoln. Rathbone was on a settee. However, I just went here - https://images.search.yahoo.com/search/i...tion=click

It does show an upholstered chair on that side. The problem that I see is that the chair has arms. If Clara sat in such a chair, it would have been a lady's chair, meaning no arms in order to accommodate her hoop skirts. Arms on chairs make skirts fly up and give an unladylike view of one's petticoats...
