Using your Casey Cotton Fitted Sheet & Pillowcase Combo is easy. First, put the fitted sheet on your Super King 50cm bed. Use the tags on the sheet to make sure it's placed correctly. Then, slip your pillows into the pillowcases. For a good night's sleep, you're all set! When it comes to maintenance, these sheets are a breeze. You can wash them in your regular washing machine. Just use a gentle cycle with a mild detergent. Avoid using bleach as it might damage the fabric. After washing, tumble dry on a low setting. This will help keep the fabric soft and maintain its durability. With proper care, your Casey Cotton bedding will last you a long time and keep you comfortable night after night.
