Answer:
Spring, in its cased form, is commonly used to fill cushions and mattresses in order to provide added support and comfort. These cased springs, also known as pocket springs, are individual coil springs encased in fabric pockets or casings.
When used in upholstery, coil springs are often integrated into the construction of furniture, such as chairs or sofas. These springs help to distribute weight evenly, offer excellent support, and enhance the overall durability of the upholstery.
Upholstering with coil springs involves securing the springs to the frame of the furniture piece with twine or wire, creating a supportive foundation. Layers of padding like foam or cotton are then added on top of the springs before the fabric is attached. This combination provides a comfortable and well-supported seating or sleeping surface.
The use of spring-filled cushions and mattresses and upholstery with coil springs is a popular choice in furniture manufacturing, as they deliver superior comfort, durability, and longevity.
