Relax Arlene Fitted Sheet SetMicrofiber sheets are low maintenance and durable. You can throw them in the washing machine without worrying about pilling or fading. They also dry very quickly after washing, saving you time when cleaning your sheets. Microfiber sheets are lightweight and breathable, but they trap more body heat than cotton sheets. Other benefits of microfiber sheets are that they are hypoallergenic, moisture wicking, stain resistant and have a silky satin feel.
