Using these sheets is a breeze. Just put the fitted sheet on your Super King 60cm bed, making sure to align it with the tags for a perfect fit. Then add the flat sheet and pillowcases. For a good night's sleep, you can smooth out any wrinkles before getting in. When it comes to maintenance, you can machine - wash these sheets in cold or warm water. Use a gentle detergent to keep the fabric soft. Avoid using bleach as it may damage the cotton. After washing, tumble - dry on a low setting. This will help maintain the durability of the sheets over time. And don't worry about shrinking, as the high - quality cotton holds its shape well through multiple wash and dry cycles.
