Victorian Pregnancy Rocking Chair

This rocking chair was given to me when I was pregnant with my last child from my stepfather who was  an antique collector.  He told me it was a "Victorian pregnancy rocker", but I was always terrified to sit in it with my big belly afraid that I would fall right through it...

It's in really good shape with the exception of the leather seat is starting to separate from the gold tacks and could use some help.  Other than that, it looks and feels strong.

I've done some research and can't seem to find another one like this anywhere and am interested in what kind of rocker it is and how much it's worth.

Many thanks!
