High back dining chairs use a 15.5 x 20.5 in backrest and an 18.5-in seat height to support a comfortable, upright posture at a standard dining table. The hollowed back design promotes airflow so you avoid feeling stuffy during long meals. A padded 17.5 x 16 in seat combines faux linen fabric with high-density sponge to create a soft yet supportive surface. Rubber wood construction, thickened 1.8-in legs, and reinforcing crossbars work together to support up to 330 lbs per chair for everyday use.
