Answer:
In the context of furniture, the term fiber typically refers to the material used to make certain types of furniture or upholstery. It usually refers to synthetic fibers that are used to create fabrics and coverings for furniture such as sofas, chairs, and mattresses. This can include materials like polyester, nylon, acrylic, or microfiber. Furniture made with fiber upholstery is often known for being durable, stain-resistant, and easy to clean. In cheap furniture fiber is sometimes used as filling for upholstery in place of hair.
