A microfiber pillow is a type of pillow made from small, lightweight fibers that are tightly twisted together. Microfiber pillows are often made of a synthetic fabric and are designed to be both comfortable and breathable. They are commonly used in place of traditional pillows because they are more comfortable to sleep on and less likely to cause allergies or other skin problems. A best microfiber pillow is lightweight, which makes it ideal for people who have back problems or other issues that make them uncomfortable when sleeping on a regular pillow.
