A pillow is a soft cushion used to support the head and neck while sleeping or resting. It is typically filled with materials like foam, feathers, or synthetic fibers, providing comfort and helping to maintain proper alignment of the spine. Pillows come in various shapes and sizes, catering to different sleeping positions and preferences. In addition to their primary function, pillows can also enhance the decor of a room. Decorative pillows, often referred to as throw pillows, are used on sofas and beds to add color and style. They can be made from various fabrics and designs, making them versatile accessories in home decor.
