Frame is crafted of steel and engineered wood. Hardware features a Matte Black finish. Height is adjustable and the chair swivels 360°. Leather is a natural product. Variation in color and texture are inherent to each hide; no two pieces are exactly alike. Semi-anilines have natural markings that vary from hide to hide. They also have color variations due to the leather’s ability to accept dyes differently in various areas of a hide. Markings and shading distinguish genuine leather from man-made materials. Appreciating shade differences among hides also means appreciating them on individual furniture pieces, because no two pieces can be produced from a single hide. Contract Grade: Thoughtfully designed and expertly engineered to meet rigorous testing standards and best practices from select ANSI/BIFMA testing protocols. Imported. CARE Never use detergents, polishes, preservers or saddle soap. They can remove natural oils. Dust or vacuum for routine maintenance. Do not place in direct sunlight; it will lighten or discolor leather over time. If spills occur, immediately soak up any liquids with an absorbent cloth and allow to air dry. Thorough cleaning by a leather specialist only. Most surface scratches will fade over time if you rub them with your fingertips. Friction and heat from rubbing helps to redistribute wax in surrounding areas to cover the scratch. Not all scratches have the same depth, and this may not work on deeper scratches.
