Breathable, quick-drying fabric on the seat and backrest lets air circulate and helps moisture dry faster, making these patio lawn chairs suitable for outdoor use. A 21 x 18 in seat with a contoured backrest and curved armrests supports a more relaxed sitting posture. The heavy-duty metal frame uses triangular structures with support rods and reinforced crossbars so each chair supports up to 350 lbs. Adjustable foot pads help the chairs adapt to slightly uneven ground for steadier contact.
