The easy answer, of course, is at the antique store, at the second-hand shop, maybe, in your attic. Not in mine, I’m sorry to say. I have a rocking chair, but it dates to 1989 and you can tell.
It isn’t very comfortable either — at least for me. At one time in my life (somewhere in the 90’s) I had a group that met regularly at my apartment. One tall young man always took this chair. Then I realized why it wasn’t comfortable for (short) me. Rocking chairs have a symbolic quality, not just because they’re what we’re supposed to be sitting in, whiling away old age. At least I choose to think that. I think they might stand for ease in company — for anybody.
Whaddya Mean Rosebuds? 
My dream (one of them anyway) is to have a front porch with several rocking chairs and a view of the neighborhood! Love that old rocking chair!
