Antique Oak Slat-Back Swivel Office Chair, 33"H

I picked up this beautiful antique oak swivel office chair. It's over 100 years old, with a slat back, solid wood seat, and a cast-iron swivel and tilt mechanism. It swivels, rolls, and leans back smoothly. The original flat casters were replaced with authentic antique wheels. The oak grain on the seat is gorgeous. There are a few small nicks on the front edge of the seat, pictured, honest wear for a chair this age and nothing structural. 33" tall overall, seat 17.5" wide by 17" deep, seat height about 18", base about 25" across wheel to wheel. No maker marks found. Local pickup in Lake Oswego.
