Using these Casey Cotton Bed Sheets is a piece of cake. Just put the fitted sheet on your Super King 50cm bed, making sure to align it according to the tags for a perfect fit. Then, lay the flat sheet on top and add your favorite pillowcases. When it comes to washing, you can toss them in the machine on a regular cycle. But remember to use a gentle detergent to keep the fabric in great shape. Avoid using bleach as it can damage the cotton. After washing, tumble dry on a low setting or hang them to dry. This way, your sheets will stay soft, durable, and ready for many more restful nights.
