This is a high-back executive office chair made of commercial-grade, durable, stain-resistant, and breathable black leather-look fabric; it meets or exceeds ANSI/BIFMA performance standards for office furniture. Ergonomically designed, its tall and wide curved backrest provides superior support, while the headrest, flip-up armrests, and an exceptionally thick, wide, and deep seat are all generously padded to deliver maximum comfort. The 360-degree swivel seat and 5-star chrome metal base with hooded casters offer mobility, while an adjustable height mechanism with tilt-back/lock-in control allows the chair to be optimized to your comfort level. Assembly is required: illustrated instructions and all hardware are provided for convenience (additional tools may be needed).
