Four slender metal spindles form the back of each dining chair, creating a Windsor-inspired look while leaving the profile open around your table. The tilted backrest and contoured 17.5 x 16.5 in seat are shaped to fit your hips to help reduce pressure during long meals. A 1-in thick panel with rounded corners rests on an X-shaped frame that ties together the bentwood, MDF, metal and rubber wood veneer structure. Each 21 x 19.5 x 35 in chair supports up to 350 lbs for dependable everyday seating.
