An Antique Sofa - unknown product

I had this sofa from a friend of the family. Unfortunatley I no longer have the room for it as I am moving into a smaller home. I would like to sell this item but I am unsure on what it is called or how much it is worth. I have tried searching all over the internet and I can not find one item like it. I do not want to sell without giving the customer the correct information. Does anyone know anything about this sofa? I also have a small chair and armchair to match.
