Using this chair is easy. Just place it where you want to sit and enjoy. Whether it's in a restaurant or at home, it'll serve you well. When sitting, the curved support bar will give you nice back support. For safety, since it has fire - retardant foam, you don't have to worry too much about fire risks. As for maintenance, keep it clean by wiping the vinyl seat with a mild cleaner. Check the welded joints from time to time to make sure they're still stable. Avoid dragging the chair across the floor; instead, lift it up to prevent damage to both the chair and the floor. The plastic glides are there to protect your floor, so make sure they're in good condition. With proper care, this chair will last you a long time.
