Edwardian Style Mahogany Corner or Desk Chair with Olive Green Velvet

This piece is a unique corner-style armchair, likely dating from the early to mid-20th century, displaying Edwardian or Art Deco design influences. The chair features a distinctive curved, asymmetrical backrest that wraps around to form a single arm, suggesting it was designed as a desk chair or corner accent piece. It is constructed from a dark-stained wood, likely mahogany or a similar hardwood, with a warm reddish-brown finish. The upholstery is a plush olive green velvet, secured with systematic brass-toned decorative nailhead trim along the borders of the seat and backrest. The chair stands on four slender, tapered square legs, each terminating in original small brass caster wheels, which indicate it was intended for easy mobility on a hard floor or rug. The craftsmanship displays solid joinery with a circular seat frame. Regarding condition, there is visible wear consistent with age: the wood finish shows scuffing and minor finish loss along the upper rim of the backrest and the seat edge. The velvet pile shows some crushing and surface debris from outdoor exposure, but appears free of major rips. The caster wheels show a darkened patina from oxidation. No visible manufacturer's marks are present in this view, but the style suggests a high-quality production piece intended for a library or study.
