Using this chair is easy. Just assemble it following the included instructions. It's suitable for both commercial dining areas and your home dining room. When using, make sure not to exceed the 500 lb weight capacity to keep it stable. Avoid dragging the chair on the floor; instead, lift it to prevent damage to the floor protector plastic glides. For maintenance, wipe the vinyl seat with a mild cleaner and a soft cloth regularly to keep it clean. Check the welded joints and support bar occasionally for any signs of wear and tear. If you notice any issues, contact our customer service for assistance.
