The wide back and comparatively short legs makes it look like a nursing chair to me.
IE for a mother (or even a wet-nurse) to sit down and breast feed a baby.
They usually have casters though, and yours doesn't. Maybe someone just cut the bottom of the legs off !!
It's been re-upholstered, not by a professional (sorry to be blunt), but I think it has a bit of age to it.
If pushed, I'd guess Edwardian.
