Using your Nova King - Size Metal Headboard is a breeze. First, assemble it as per the included instructions. You'll need to put in a bit of effort during assembly, but once it's done, you're good to go. When adjusting the height, simply choose one of the seven mounting positions that best suits your bed and personal preference. This headboard works great with all types of bedding, so feel free to mix and match. For maintenance, keep it clean by wiping it with a soft, dry cloth regularly. Avoid using harsh chemicals as they might damage the powder - coated finish. Also, make sure the area around the headboard is dry to prevent rusting. If you move the bed or headboard, be careful not to hit it against hard surfaces to avoid dents or scratches. Enjoy your stylish and functional headboard!
