Using your Casey Cotton Fitted Sheet & Pillowcase Combo is a breeze. First, put the fitted sheet on your single 50cm bed, using the tags on each side to make sure it's correctly placed. Then, slide your pillows into the pillowcases. For a great night's sleep, just hop in! When it comes to washing, you can use a regular cycle in your washing machine. We recommend using a mild detergent to keep the fabric in top condition. Avoid using bleach as it can damage the cotton. After washing, tumble dry on a low - heat setting. This combo is designed to be durable, but try not to over - stretch the fabric when handling it. With proper care, these sheets will last you a long time and keep providing you with a comfortable sleep experience.
