Embrace the sophisticated and contemporary style of the Stairatt Gravel Chair with its polyester upholstery, corner-blocked frame, attached back and loose seat cushions. Providing pristine support, the high-resiliency foam cushions are wrapped in thick poly fiber while the platform foundation system resists sagging 3x better than any spring system. The smooth platform foundation maintains a tight, wrinkle-free look without dips or sags that can occur over time with sinuous spring foundations.
