My Unidentied Antique Loveseat

I fell in love with this loveseat and am in the process of restoring it but I'm having a hard time dating it and figuring out the style. It's coil springs, 8 way hand tied, the twine is so old it's practically turning to dust. Hand carved wood, walnut I believe by the markings and color. Some of the edges look uneven which leads me to believe it may be older, held down by both tacks and staples, never reupholstered. There's some type of finish on the wood, though not a shine or gloss. Maybe a wax? Looks and feels very smooth. Stuffed with 2 layers of horsehair and what looked like burlap in between, also cotton batting that I saved to reuse. All four feet have metal protector things on the end, which have a little circle at the bottom. No labels found. Any help is much appreciated!
