My Grandma's chair

This was my great grandma's chair that I would like to have reupholstered. It has horse hair for the seat cushion, to keep the value of the chair can I do a mixture of horse hair and foam? It is heavy, has beautiful carved arms, nailhead trim. On the seat of the chair there is a label that said Chicago Futorian but it doesn't look like Morris Futorian's style. I am wondering if he reupholstered it at one time? Can anyone identify the style, chair, etc? I would love any thoughts.
