Using these Casey cotton fitted sheets is a piece of cake. Just stretch the sheet over your king - sized 40 - cm deep bed, using the tags to make sure it's properly aligned. For a good night's sleep, simply make your bed as you normally would. When it comes to maintenance, you can easily throw these sheets in the washing machine. Use a gentle cycle with a mild 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. With proper care, these sheets will stay soft, comfortable, and durable for a long time.
