Four black Windsor dining chairs combine an ergonomic high spindle back and a curved semi-circle top rail to support natural body curves while you sit at the table. Each chair uses a large 18 x 18 in seat and an 18-in seat height to provide ample sitting space and a comfortable posture. Solid rubber wood construction and reinforced H-shaped crossbars between the legs enhance overall stability so each chair supports up to 330 lbs. A smooth, splinter-free surface makes cleaning quick and easy.
