Using your Casey Cotton Fitted Sheet and Pillowcase Combo is a breeze. First, place the fitted sheet on your queen - sized 40cm bed. Use the convenient tags to make sure it's correctly positioned. Then, put your pillows into the pillowcases. For a good night's sleep, simply get into bed and enjoy the cool, breathable cotton. When it comes to maintenance, you can easily machine - wash these sheets in cold or warm water. Use a gentle detergent to keep the fabric in great condition. Avoid using bleach as it may damage the cotton. After washing, tumble dry on low heat or hang them to dry. This will help maintain the durability of the sheets and keep them looking and feeling great for a long time.
