Two Windsor dining chairs pair a wide 17.5 x 17 in swivel seat with an 18-in seat height so you can turn toward the table or conversation without moving the chair base. Solid rubber wood construction and an X-shaped underframe support up to 330 lbs per chair for dependable daily use. The inclined spindle backrest measures 17 x 17.5 in to provide curved support, while round corners and non-slip foot pads help make sitting and standing more comfortable and protect hard floors from scratches.
