Nichols & Stone Rocker

I acquired this rocking chair from my grandmother when she passed away.  I have tried to research myself but I am very confused as the only other ones I see of the same style are noted as child rockers which this seems to big to be a childs rocker.  It is a Nichols & Stone rocker and in very good shape.  I have provided a picture of the chair and picture of the bottom of the chair.  If your not a KU fan I apologize upfront.  :)

The measurements are:

floor to seat: 14.5 inches

Seat to top of back of chair: 29 1/4 inches

Floor to top of back of chair: 44 inches

I would love to determine if this is truly a childs chair or an adult chair and what the value might be as I almost sold it for $40.00. 

Good
