Supersoft™ is a type of microfiber fabric made from very fine synthetic fibers. Because the fibers are so small, the fabric is much denser, which means that less dust or other allergens can penetrate the fabric, making your furniture more allergy-friendly.
Another advantage of the dense fabric is that liquids remain on the surface instead of immediately penetrating the fibers, giving you some time to clean up the liquid before it stains. The material also retains its color well and will look fresh and new for longer than many other fabrics.
