Using these chairs is super easy. Just place them around your dining table and sit back to enjoy your meals. When sitting, make sure to adjust your posture so that your spine fits well into the contoured seat - back for maximum comfort. As for maintenance, use a soft, dry cloth to wipe the leatherette upholstery regularly to keep it clean. Avoid using harsh chemicals or abrasive cleaners as they can damage the leatherette. If there are any spills, clean them up immediately. Also, try not to drag the chairs on the floor to prevent scratching the chrome - finished legs. With proper care, these chairs will serve you well for a long time.
