Tyynynpäällinen

Tyynynpäällinen is a textile cover for a pillow, designed to encase a pillow insert and protect it while providing a finished appearance. In everyday use it refers to covers for both bed pillows and decorative cushions, and it is commonly sold as part of a bedding set.

Most tyynynpäälliset are of envelope style, with an opening at one end. Alternative closures may include a zipper, buttons, or a concealed flap, depending on the design and manufacturer.

Fabrics used include cotton, cotton blends, linen, and satin, as well as materials such as flannel or velvet for decorative purposes. The choice of fabric affects feel, durability, and ease of care. Pillowcases are produced in a range of sizes to fit standard pillow inserts and decorative cushions, with finishes ranging from plain and printed to textured or embroidered.

The Finnish word tyynynpäällinen combines tyyny (pillow) and päällinen (cover or outer layer).

Care and maintenance: Pillowcases are designed to be machine washable. Follow fabric care labels, using appropriate water temperature and a gentle cycle; tumble drying on low or line drying is common. Washing separately by color and avoiding fabric softeners can extend the life of the fabric.

Historically, pillow covers have existed in many cultures for centuries, and modern mass production has made them widely available in a variety of styles and fabrics.
